If you've spent any time in crypto, you've seen friends or strangers buying "the next 100x" altcoin. Most of those don't 100x. Most lose money — sometimes all of it.
This isn't a moral judgment. Altcoins are speculative. Some win big. Most don't. The math just doesn't lie: the median altcoin underperforms Bitcoin over any multi-year horizon by a wide margin.
If you still want to take altcoin bets — fine, many people do — these four questions filter out the obvious bad ones without making you read a whitepaper.
Question 1: Why does this need to exist?
Specifically: what does this token do that Bitcoin or Ethereum doesn't already do?
The honest answer for many altcoins is "nothing — it's just a token that got marketed well." That's not a fatal flaw on its own, but it should make you nervous about its long-term staying power.
The honest answer for a smaller set is "it does this specific thing that Ethereum can't do well, and the demand for that thing is real." Solana's case for being faster and cheaper. Monero's case for being private. Chainlink's case for connecting blockchains to real-world data.
If you can't answer this question after 10 minutes of looking at the project, don't buy it. The 10-minute test is real.
Question 2: Who controls the supply?
For Bitcoin and Ethereum, the supply schedule is transparent and pre-determined. Nobody can decide to print more.
For a lot of altcoins, the answer is "the team can print more whenever they want," or "40% of the supply is held by insiders who can sell anytime they want."
Two specifics to check:
-
The token-holder concentration. Tools like Etherscan and Solscan let you look at the top wallets. If 5 wallets hold 50% of the supply, and you don't know who they are, you're betting they don't sell. That's a different bet than you thought you were making.
-
The "unlock schedule." Many altcoins have insider tokens that vest over years. When they unlock, those insiders often sell. Look up the unlock schedule. If a big unlock is coming in the next 3 months, the price typically suffers around it.
If either answer makes you uncomfortable, take it as a no.
Question 3: What's the team's track record?
Look up the founders. Have they shipped real software in the past? Do they post regularly with technical substance, not just hype? Are they pseudo-anonymous, and if so, why?
Pseudo-anonymity isn't automatically bad — some real projects have pseudonymous founders. But it does mean you have less to fall back on if things go wrong.
What you don't want:
- Founders who have launched multiple previous tokens that went to zero
- A team that has never built software but has a lot of marketing copy
- Anonymous founders with no on-chain track record either
What you do want:
- Real-name founders with real LinkedIn pages and verifiable past employment
- Or pseudonymous founders with multi-year, verifiable on-chain contribution histories
Question 4: Where does the buying pressure come from?
This is the question almost nobody asks, and it's the most useful one.
For a token's price to go up sustainably, more dollars need to flow in than flow out. Not "more buyers than sellers" — every trade has a buyer and seller. Net new dollars.
Where do net new dollars come from?
- For BTC and ETH: institutional flows (ETFs), retail entry, treasury allocations, real users storing wealth in the asset.
- For most altcoins: other speculators, hoping to sell to even later speculators. This is the structure of every "narrative pump."
If the only reason new money is flowing in is that other people are flowing money in, you're in a pyramid where you need to be early. The math of being early in 10 trades is: most of the 10 don't work, and 1 makes up for it. Unless you can actually be that disciplined, the expected value isn't great.
For a token with real economic activity — protocol fees being paid in it, actual users buying things — there's a structural reason for net flows. For a token with just speculation, there isn't.
A useful summary checklist
Before buying any altcoin, write down:
- What does this do that BTC/ETH don't?
- Who controls the supply, and when does it unlock?
- Who's the team, and what have they built before?
- Where are the real, non-speculative dollar inflows?
If three of four answers are "I don't know" or "they're concerning," don't buy. If you're going to buy anyway, size the position so a 100% loss doesn't change your life — because the base rate is exactly that outcome.
The honest summary
Most altcoins are bad investments. Some are good. The ones that are good usually have honest answers to the four questions above. The ones that are bad rarely do.
You can absolutely make money on altcoins. The historical pattern is: 1-2 work spectacularly per cycle, the rest lose. The key is sizing them so you can survive the losses while staying in the game for the wins.
None of this is financial advice. Most altcoins go to zero. Most. Treat them like venture-capital bets, not savings accounts.
