Cryptocurrencies & Bitcoins
introduction
“Congratulations, if you made it this far on my website, you are going in the right direction. I will assume you are either an investor in cryptocurrencies, someone who is thinking of investing in cryptocurrencies, or you are a lawyer who represents an investor who has lost a lot of money investing in cryptocurrencies. I should be able to help all of you. There are numerous places on this website that talk about my experience and expertise, and you also can find a number of accolades and differences from investors and lawyers I have worked for during my 40 years of helping lawyers and investors. In addition to being a registered and licensed stockbroker, I was also a registered and licensed commodities broker. This is useful because cryptocurrencies are now covering both professions. In my professional career, I have personal extensive experience in both securities and commodities with both the speculative trading side and various hedging strategies. Call for a free consultation
risk & Danger for cryptocurrencies investing in bitcoins can be dangerous to your financial health
There are all kinds of adjectives that can be used to describe the incredible surge in interest in bitcoins in just the past year: bubble mentality, foaming at the mouth, excessive exaggeration, out of control and off the charts, just to mention a few. At the young age of 73, I have witnessed personally previous bubbles which have been disastrous for investors. And as a securities expert, I have studied extensively bubble driven investment fiascoes.
There was the tulip bulb mania in the early 1600’s in Europe, which is often considered one of the first financial speculative bubbles in history. In the United States, one of the first bubbles was the railroad stocks and bonds, where Americans lost millions. There was the Hunt brothers silver crash in 1980, started and orchestrated by the Hunt brothers who tried to corner the market in silver. As the Hunts tried to corner the market on silver they drove the price of silver up. Thousands of investors jumped on the bandwagon only to lose millions when the market crashed. More recently, we had the telecom and technology bubble and stocks that fizzled in 2001. And of course, we all remember firsthand the subprime debt related real estate bubble/bust in 2007.
Despite this, everyone is jumping on the bitcoin bandwagon. The CFTC recently approved trading futures on bitcoins. As of 2024, investors can now trade in bitcoin ETFs. It is this last item that concerns me the most. Opening an ETF to every single American who has a brokerage account is exposing millions to this very dangerous, speculative and volatile market.
I am not condemning the cryptocurrency of bitcoins or any other related product. And I am not questioning its use as a currency. I am only warning investors about utilizing these instruments as investments, albeit speculative ones. I will be researching and writing about bitcoin in the near future, but for now keep in mind that a very large percentage of the people who are buying and speculating in bitcoins are in Southeast Asia. The Southeast Asian investment markets are known for unregulated and excessive bubbles. The mere fact that bitcoin and cryptocurrencies have had phenomenal run ups in value in just the last two years alone should give investors cause for concern from an investing standpoint.
The mere fact that some lucky investors made millions because they were on the front end of many of the cryptocurrency startup operations does not mean you should jump on the bandwagon. There is an age-old warning for investors who chase ever increasing investments; don’t be the last man in. At some point in the future, some of the remaining cryptocurrencies may become legitimate investment vehicles. At this point, as trading vehicles, they are nothing more than speculative investments.
Here is an interesting article from the Wall Street Journal:
The Boom in Crypto ETFs Has a Downside for Investors
Investors face higher costs and the unwelcome prospect of fund closures as more digital-asset funds come to market
By Tanzeel Akhtar June 4, 2026 2:00 pm ET Wall Street Journal
Kiersten Essenpreis for WSJ
Many crypto ETFs launched since January 2024 face closure risk, with analysts predicting up to a third could shut within two years.
A boom in cryptocurrency exchange-traded funds has given investors more ways to buy digital assets over the past 2½ years. But more isn’t always better.
The problem for investors is that many of these new funds carry higher fees, as well as the risk of closure for funds that don’t gain traction.
Since U.S. regulators approved spot crypto funds—those investing in a single cryptocurrency—in January 2024, asset managers have launched 130 funds and attracted tens of billions of dollars in assets. And asset managers are racing to replicate that success with 155 digital-asset ETFs in the pipeline, according to Morningstar Direct data.
But investor demand remains concentrated in low-cost bitcoin and Ethereum products from major issuers such as BlackRock and Fidelity Investments, leaving many newer products struggling to attract meaningful assets or reach viable scale. Analysts warn that as many as a third of crypto ETFs could shut within two years, leaving investors with an unwelcome disruption.
Fund closures force investors out of their positions—potentially triggering capital-gains taxes and possibly leading them to find replacement exposure, often during turbulent markets.
“When a fund closes, it’s liquidated,” says Elisabeth Kashner, director of global fund analytics at FactSet. “The portfolio manager will sell the positions, turn everything to cash, and that will go out to clients sort of the same way that a dividend payment would.”
Survival of the biggest
The crypto ETF market reflects investors’ preference for low-cost funds. Within spot bitcoin ETFs, BlackRock commands nearly 60% of market share, with Fidelity capturing an additional 13%—meaning the two firms together control roughly 72% of overall spot bitcoin ETF assets, according to FactSet data. The biggest funds, BlackRock’s iShares Bitcoin Trust ETF (ticker:
IBIT) and Fidelity Wise Origin Bitcoin Fund (FBTC), both charge annual fees of about 0.25%, putting pressure on higher-cost competitors.
The fee pressure has created casualties even among established players. Grayscale Bitcoin Trust ETF (GBTC), one of the original crypto funds before spot ETFs gained approval, still charges1.5% annually—six times as high as competitors. The fund has seen more than $26.3 billion innet outflows since January 2024 as investors migrated to cheaper alternatives.
The average bitcoin ETF holds about $8 billion in assets, according to Bloomberg Intelligence, nearly three times the $3 billion average for U.S. ETFs generally. By contrast, many altcoin-focused funds—products tracking cryptocurrencies other than bitcoin and Ethereum—havestruggled to attract investor dollars.
Products typically need at least $25 million to $100 million in assets to remain economically viable, says Daniel Sotiroff, senior manager research analyst at Morningstar, though the exact threshold depends on the issuer’s size and willingness to subsidize underperforming funds. Manyrecently launched crypto ETFs fall well short of that range.
“Generally speaking, about a quarter of all ETFs liquidate,” says Eric Balchunas, senior ETF analyst at Bloomberg Intelligence. “In a category like this, where there’s such a land rush, you’re probably looking at 30% to 35% that will cease to exist in a couple of years.”
So far a dozen U.S. crypto ETFs have shut, according to FactSet, but the industry’s next phase may be harsher: The firm’s analysis shows 34 crypto ETFs currently trading are at high risk ofclosure.
Understanding the risks
While investors don’t lose their money when ETFs liquidate, unexpected closures can be disruptive. Liquidation can force investors to realize capital gains in that tax year if the ETF had gained in value, even if they would have preferred to keep holding. That could generate an unexpected tax bill in taxable accounts.
What’s more, a liquidation could disrupt an investor’s portfolio allocation. While crypto is likely a small portfolio allocation for most investors—typically 1% to 5%, according to analysts—restoring that allocation could be costly given the volatility of digital assets.
Investors who want to maintain their allocation may need to quickly find a replacement fund, potentially incurring additional trading costs or re-entering the market at less favorable prices if prices have moved sharply.
Beyond closure risk, thinly traded crypto ETFs often carry hidden costs. Funds with limited trading volume typically have wider bid-ask spreads—or the difference between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept for an asset—making them more expensive to buy and sell.
“When you have products that are functionally identical, do a deep dive into the operating efficiency and the trading costs,” Kashner says. “Look for low expenses, look for low trading spreads.”She explains that investor buying and selling serves as an early warning system for a fund’s future. “In general, when flows are positive, an asset manager might have more patience with a product,” she says. “Whereas if flows are nonexistent or negative, you know that it’s harder to keep a fund open on hope alone.”

Bitcoins Terms Glossary
Here is your guide to some of the key terms and concepts underpinning this exciting world of investing.
Altcoin
Altcoin is a form of cryptocurrency that has the same decentralized, peer-to-peer principles as bitcoin, but which uses its own blockchain and has its own rules of operation.
Bitcoin
Bitcoin is a form of digital currency created in 2009, that is created and distributed on a peer-to-peer basis.
It has no central bank – transactions are conducted directly between individuals. Bitcoin is the most popular kind of cryptocurrency.
Block
Blocks are found in the Bitcoin block chain. Blocks connect all transactions together. Transactions are combined into single blocks and are verified every ten minutes through mining. Each subsequent block strengthens the verification of the previous blocks, making it impossible to double spend bitcoin transactions (see double spend below).
BIP
Bitcoin Improvement Proposal or BIP, is a technical design document providing information to the bitcoin community, or describing a new feature for bitcoin or its processes or environment which affect the Bitcoin protocol. New features, suggestions, and design changes to the protocol should be submitted as a BIP. The BIP author is responsible for building consensus within the community and documenting dissenting opinions.
Block Chain
The Bitcoin block chain is a public record of all Bitcoin transactions. You might also hear the term used as a “public ledger.” The block chain shows every single record of bitcoin transactions in order, dating back to the very first one. The entire block chain can be downloaded and openly reviewed by anyone, or you can use a block explorer to review the block chain online.
Block Height
The block height is just the number of blocks connected together in the block chain. Height 0 for example refers to the very first block, called the “genesis block.”
Block Reward
When a block is successfully mined on the bitcoin network, there is a block reward that helps incentivize miners to secure the network. The block reward is part of a “coinbase” transaction which may also include transaction fees. The block rewards halves roughly every four years; see also “halving.”
Change
Let’s say you are spending $1.90 in your local supermarket, and you give the cashier $2.00. You will get back .10 cents in change. The same logic applies to bitcoin transactions. Bitcoin transactions are made up of inputs and outputs. When you send bitcoins, you can only send them in a whole “output.” The change is then sent back to the sender.
Cold Storage
The term cold storage is a general term for different ways of securing your bitcoins offline (disconnected from the internet). This would be the opposite of a hot wallet or hosted wallet, which is connected to the web for day-to-day transactions. The purpose of using cold storage is to minimize the chances of your bitcoins being stolen from a malicious hacker and is commonly used for larger sums of bitcoins.
Confirmation
A confirmation means that the bitcoin transaction has been verified by the network, through the process known as mining. Once a transaction is confirmed, it cannot be reversed or double spent. Transactions are included in blocks.
Cryptocurrency
Cryptocurrency is the broad name for digital currencies that use blockchain technology to work on a peer-to-peer basis. Cryptocurrencies don’t need a bank to carry out transactions between individuals. The nature of the blockchain means that individuals can transact with each other, even if they don’t trust each other. The cryptocurrency network keeps track of all the transactions and ensures that no one tries to renege on a transaction.
Cryptocurrency 2.0
Also known as a decentralized app, a cryptocurrency 2.0 project uses the blockchain for something other than simply creating and sending money. They typically involve decentralized versions of online services that were previously operated by a trusted third party.
Cryptography
Cryptography is used in multiple places to provide security for the Bitcoin network. Cryptography, which is essentially mathematical and computer science algorithms used to encrypt and decrypt information, is used in bitcoin addresses, hash functions, and the block chain.
Decentralized
Having a decentralized bitcoin network is a critical aspect. The network is “decentralized,” meaning that it’s void of a centralized company or entity that governs the network. Bitcoin is a peer-to-peer protocol, where all users within the network work and communicate directly with each other, instead of having their funds handled by a middleman, such as a bank or credit card company.
Difficulty
Difficulty is directly related to Bitcoin mining (see mining below), and how hard it is to verify blocks in the Bitcoin network. Bitcoin adjusts the mining difficulty of verifying blocks every 2016 blocks. Difficulty is automatically adjusted to keep block verification times at ten minutes.
Double Spend
If someone tries to send a bitcoin transaction to two different recipients at the same time, this is double spending. Once a bitcoin transaction is confirmed, it makes it nearly impossible to double spend it. The more confirmations that a transaction has, the harder it is to double spend the bitcoins.
Full Node
A full node is when you download the entire block chain using a bitcoin client, and you relay, validate, and secure the data within the block chain. The data is bitcoin transactions and blocks, which is validated across the entire network of users.
Halving
Bitcoins have a finite supply, which makes them scarce. The total amount that will ever be issued is 21 million. The number of bitcoins generated per block is decreased 50% every four years. This is called “halving.” The final halving will take place in the year 2140.
Hash Rate
The hash rate is how the Bitcoin mining network processing power is measured. In order for miners to confirm transactions and secure the block chain, the hardware they use must perform intensive computational operations which is output in hashes per second.
Mining
Bitcoin mining is the process of using computer hardware to do mathematical calculations for the Bitcoin network in order to confirm transactions. Miners collect transaction fees for the transactions they confirm and are awarded bitcoins for each block they verify.
Pool
As part of bitcoin mining, mining “pools” are a network of miners that work together to mine a block, then split the block reward among the pool miners. Mining pools are a good way for miners to combine their resources to increase the probability of mining a block, and also contribute to the overall health and decentralization of the bitcoin network.
Private Key
A private key is a string of data that shows you have access to bitcoins in a specific wallet. Think of a private key like a password; private keys must never be revealed to anyone but you, as they allow you to spend the bitcoins from your bitcoin wallet through a cryptographic signature.
Proof of Work
Proof of work refers to the hash of a block header (blocks of bitcoin transactions). A block is considered valid only if its hash is lower than the current target. Each block refers to a previous block adding to previous proofs of work, which forms a chain of blocks, known as a block chain. Once a chain is formed, it confirms all previous Bitcoin transactions and secures the network.
Public Address
A public bitcoin address is cryptographic hash of a public key. A public address typically starts with the number “1.” Think of a public address like an email address. It can be published anywhere and bitcoins can be sent to it, just like an email can be sent to an email address. Learn how to receive bitcoin in your bitcoin wallet here.
Satoshi Nakamoto
Bitcoin’s existence began with an academic paper written in 2008 by a developer under the name of Satoshi Nakamoto. Satoshi is the name used as the original inventor of Bitcoin. You can learn more about Satoshi here.
Transaction
A transaction is when data is sent to and from one bitcoin address to another. Just like financial transactions where you send money from one person to another, in bitcoin you do the same thing by sending data (bitcoins) to each other. Bitcoins have value because it’s based on the properties of mathematics, rather than relying on physical properties (like gold and silver) or trust in central authorities, like fiat currencies.
Wallet
Just like with paper dollars you hold in your physical wallet, a bitcoin wallet is a digital wallet where you can store, send, and receive bitcoins securely. There are many varieties of wallets available, whether you’re looking for a web or mobile solution. Ideally, a bitcoin wallet will give you access to your public and private keys. This means that only you have rightful access to spend these bitcoins, whenever you choose to.
