In crypto, position sizing matters more than entry timing. Master the math that keeps one bad trade from ever ending your account.
Risk no more than 1–2% of your account on any single trade. Be precise about the word risk: it means the dollars you'd lose if your stop is hit — not the dollars in the position. Why it matters: a $10,000 account risking 1% per trade can absorb 100 losses in a row before going broke. Risk 10% instead, and just 10 losses end you. Same trader, same strategy — only the sizing changed.
Behind the 1% rule sits a real branch of probability theory called risk of ruin — the odds that a string of bad luck wipes you out before your edge can play out. The key insight is that survival isn't linear, it's exponential: cut your risk per trade in half and you don't halve your chance of ruin, you crush it dramatically, because you'd need twice as many losses in a row to die. Even a genuinely skilled trader who wins 55% of the time will hit a losing streak of 8 or 10 eventually — variance guarantees it. The 1% rule exists so that when (not if) that streak arrives, it's a bruise, not a funeral.
This connects to a deeper idea traders borrow from gambling math: the difference between the average outcome and the outcome you actually live through. A bet can have a great average and still ruin most people who take it, because you only get one path through time and ruin is a trapdoor you can't climb back out of. Once you're at zero you're out — forever — no matter how good the strategy looked on paper. That's why professionals obsess over surviving the worst case, not maximizing the average case.
Sizing isn't a vibe; it's arithmetic. Pick your risk in dollars, measure the distance to your stop, and the position size falls out automatically.
The formula looks tidy, but crypto sneaks in a variable that ruins it if you ignore it: slippage. Your stop says $0.92, but on a thin-liquidity token during a fast drop, the price can gap straight past your stop and actually fill at $0.87 — so your "1% risk" quietly became 1.6%. This is why sizing math and liquidity can't be separated: a stop is only as reliable as the depth of buyers sitting beneath it. Serious traders check the order-book depth, or a token's daily volume, before trusting a stop level at all. On a deep asset like BTC a stop is nearly exact; on a micro-cap it's a hope.
There's a famous formula, the Kelly criterion, that calculates the mathematically "optimal" bet size from your edge and odds. It's worth knowing about — and worth deliberately under-using. Full Kelly is wildly aggressive and assumes you know your true win rate exactly, which in crypto you never do. Professionals run "fractional Kelly," often a quarter or less, precisely because the penalty for over-betting (ruin) is so much worse than the penalty for under-betting (slightly slower growth). The fixed 1% rule is really just a simple, robust cousin of fractional Kelly.
Lose 50% and you don't need 50% back — you need 100% just to break even. The deeper the hole, the more violently the required recovery accelerates. This asymmetry is exactly why a single oversized, ungated trade can scar a portfolio for years.
| Drawdown | Gain needed to recover |
|---|---|
| -25% | +33% |
| -50% | +100% |
| -70% | +233% |
| -90% | +900% |
The asymmetry has a precise cause, and it's just how percentages compound. When you lose 50%, the base your recovery grows from is now only half as big — so a +50% gain on that shrunken base only gets you back to 75%, not 100%. The recovery has to overcome the loss and the smaller starting point at once. The formula is exact: recovery needed = 1 ÷ (1 − loss) − 1. That's why −25% needs +33%, −50% needs +100%, and −90% needs a brutal +900%. Each additional chunk of drawdown makes the hole disproportionately deeper, which is the mathematical heart of "protect the downside."
This is also why volatility itself silently taxes you, an effect called volatility drag. A coin that drops 50% and then rises 50% is not back to even — it's down 25%. Wild up-and-down swings erode a portfolio even when the average return looks fine, which is another reason position sizing and drawdown control matter more than picking hot entries. Keeping your drawdowns shallow isn't just about comfort; it's the difference between compounding forward and spending years just clawing back to zero.
Place stops below market structure — the last swing low or a support cluster — not at the obvious round numbers where everyone else's stops sit and get hunted. And take profit by scaling out, never all at once.
Here's a truth most beginners learn the hard way: stop-hunting is real. Because everyone places stops at the obvious spot — just under the round number, just under yesterday's low — that spot becomes a magnet. Large players can briefly push price down into that cluster, triggering a wave of forced sell orders (your stop is a market sell), scooping up the cheap coins, and letting price rebound. Your stop wasn't unlucky; it was liquidity someone came to collect. The defense is to hide your stop below market structure — beneath a real swing low or support zone — where it's protected by other people's buying rather than sitting in the obvious kill-zone.
Scaling out solves a different, subtler problem: regret works both ways. Sell everything and it keeps climbing — you're sick. Sell nothing and it reverses — you're sick. Selling in tranches guarantees you'll never be fully wrong in either direction, which is precisely why it's psychologically sustainable: you always did partly the right thing. A useful upgrade is the trailing stop on your final runner — it ratchets up as price rises but never down, so it locks in gains while leaving room for a big trend to run. That trailing-and-laddering logic is exactly what Brigitte automates on the CryptoLwa exit desk.
For most people, a sensible total crypto allocation is 5–20% of liquid net worth; past about 30%, a crypto winter starts to affect your real life. Treat leverage with deep suspicion: consider it only after a year of profitable spot trading, start at no more than 2×, and never on micro-caps.
1. With a $5,000 account and 2% risk per trade, your max loss per trade is:
2. After a -50% drawdown you need a gain of:
3. The right time to think about exit is:
The 1% rule governs a single trade, but a second layer governs your life: how much crypto should exist at all. The finance concept is correlation — in a real crash, crypto assets tend to fall together, so holding ten different alts is not ten separate bets, it's closer to one big bet wearing ten hats. That's why "diversifying" across a dozen micro-caps offers far less protection than people think, and why capping total crypto at 5–20% of liquid net worth is the real diversification — the rest of your wealth sits in things that don't crash on the same day.
Leverage deserves its own fear, because it attacks survival directly. Borrowed money adds a liquidation price — a level where the exchange force-sells your entire position to protect its loan, often at the worst possible moment. At 2× leverage a 50% drop wipes you out; at 10× a mere 10% move does. And crypto routinely moves 10% in an hour. Leverage doesn't just amplify gains and losses symmetrically — it introduces a hard floor that can delete a position that would have fully recovered on spot. The rule of thumb: earn a year of profitable spot trading first, then start at no more than 2×, and never on illiquid coins. This survival-first philosophy is the same one MAZAKA hard-codes: capital preservation before every other goal.
