Bitcoin vs. Ethereum: two different goals
Bitcoin was created with a specific goal: to be a scarce, censorship-resistant digital store of value with a fixed maximum supply. Ethereum pursues something different: to be a platform on which smart contracts, code that executes automatically once certain conditions are met, can be built.
That programmability is the foundation of decentralized finance (DeFi): lending, asset swaps, or insurance that work without a traditional central intermediary. It is also the foundation of non-fungible tokens (NFTs), digital certificates of ownership over a unique asset.
What altcoins are and why most don't survive
Altcoins is the term for any cryptocurrency other than Bitcoin, and today there are several thousand of them. The vast majority have no clearly differentiated use case, show very thin liquidity outside their popularity peaks, and history shows that a large share of the ones that were popular in previous cycles have lost nearly all their value or stopped existing altogether.
This doesn't mean no altcoin has real value, but the analysis demands far more judgment than typical industry marketing suggests, and the odds of correctly identifying in advance which ones will survive are low.
- An anonymous team or one with no verifiable track record behind the project.
- Promises of guaranteed or extraordinary returns in a short time.
- No identifiable use case beyond speculation on the price itself.
- Trading volume concentrated on lightly regulated or hard-to-audit platforms.
Stablecoins: the piece that connects crypto to real money
Stablecoins are cryptocurrencies designed to maintain a stable peg to a reference asset, almost always the US dollar. They are used mainly as a fast way to move value between exchanges and as a temporary refuge within the crypto ecosystem without converting back to traditional fiat money on every trade.
Not all stablecoins are backed the same way: some hold reserves of liquid assets equivalent to the value issued, while others (algorithmic stablecoins) try to maintain the peg through market mechanisms without an equivalent direct backing, a design that has proven considerably more fragile.
if the market stops trusting that a stablecoin genuinely holds enough reserves to back every unit issued, a wave of selling can break the 1-to-1 peg with the dollar, leaving holders with an asset worth less than its name suggests.
The risks that don't make it into the bullish headlines
Beyond price volatility, investing in cryptocurrencies carries risks of a different nature than a bank deposit or a regulated ETF: custody risk (losing your wallet's private key means losing access to the money forever, with no deposit guarantee scheme to fall back on), counterparty risk on exchanges (which can be hacked or go bankrupt), and a regulatory framework still evolving in many jurisdictions.
- No deposit guarantee scheme equivalent to a bank account.
- Every trade or swap between cryptocurrencies can trigger a taxable event, unlike transfers between mutual funds.
- Historical volatility is significantly higher than that of a diversified equity portfolio.
How it fits, if at all, into your net worth
This is not investment advice. If you decide to hold exposure to cryptocurrencies beyond Bitcoin, treat them for what they are: a high-risk, highly volatile asset, held as a small, deliberately capped slice of your overall wealth strategy, never as a substitute for your emergency fund or the stable core of your portfolio.
Recording them as just another asset within your net worth, at its current value, is the only way to know how much weight they really carry within everything you own, rather than looking at them in isolation.

Frequently Asked Questions
Not necessarily safer, just different: Bitcoin prioritizes simplicity and scarcity as a store of value, while Ethereum adds the complexity (and additional risk) of running programmable smart contracts.
It stands for decentralized finance: applications built on platforms like Ethereum that replicate financial services (lending, exchanges, insurance) without a traditional central intermediary, run instead by smart contracts.
They do carry risk: the risk that the issuer doesn't actually hold the reserves it claims, or the risk of an algorithmic design failing under market stress, both capable of breaking the promised peg.
This is not investment advice. Given it's a high-risk, highly volatile asset class, it should represent, if anything, a small and deliberately capped share of your total net worth, matched to your real risk tolerance.
