Buying crypto is easy. Holding it through a bad month is the part that separates investors from tourists. If you’ve been watching from the sidelines and you’re finally ready to put real money in, the structure below is what I’ve settled on after a few cycles of getting parts of it wrong.
Decide your risk budget first
Pick a percentage of your money you can lose without changing your life. For someone just starting out, that usually lands somewhere between 1% and 10% of net worth. The exact number matters less than being honest about it. If a 50% drawdown would wreck your emergency fund or your sleep, the allocation is too big, whatever the strategy says.
Write the number down before you buy anything. Every decision after that gets easier once the ceiling is fixed.
Split the allocation into three buckets
I keep three buckets: a core, a set of bets, and a cash layer. The core is Bitcoin and Ethereum, usually 60% to 70% of the crypto allocation. Those two have the deepest liquidity, the longest track records, and the least chance of going to zero overnight.
The bets bucket holds 20% to 30%, spread across smaller positions you have an actual thesis on. The cash layer is stablecoins, 10% to 20%, parked somewhere you can reach in a day. It gives you dry powder when the market hands out discounts, and it’s the part that turns a crash from a crisis into an opportunity.
Size the small positions like a professional
Cap every speculative position at 1% to 3% of your total portfolio. Ten moonshots at 10% each is a lottery ticket collection, and it will force you to stare at charts all day. Four or five positions you understand and can explain to a friend is plenty.
When a small bet does a 5x, trim it back to target. Letting a winner grow into a third of your net worth by accident is how a good year sets up a terrible one.
Write down why you own each thing
One paragraph per position, written before you buy. The thesis, the size, the price at which you were wrong. When the market drops 40% and a friend sends you a token pitch at 11 p.m., that note is what stops you from averaging into noise. It also makes the sell decision mechanical later, when emotion is expensive.
Rebalance on a schedule
I rebalance once a quarter and after any 30% move in either direction. Rebalancing forces you to sell a little of what’s up and buy a little of what’s down. It feels wrong every single time and works anyway. If you’d rather automate the buying side, dollar cost averaging splits your entry across weeks instead of one unlucky afternoon (Wikipedia’s walkthrough covers the mechanics, and the same logic applies to crypto).
Track the positions in one place rather than across five apps. A CoinGecko portfolio with target percentages marked takes ten minutes to set up and removes the guesswork from every rebalance.
Test the portfolio in a red month
A portfolio is only real once you’ve seen the plan against a crash. Run the thought experiment now: Bitcoin falls 40% in three weeks, your alt positions fall 60%, and the headlines get ugly. What do you do? If the answer is sell everything, the allocation is wrong before the crash arrives. If the answer is rebalance and maybe add, you’ve built something you can hold.
The bottom line
Pick your risk number, split it into core, bets, and cash, size the small stuff at 1% to 3%, and rebalance on a calendar. None of that is exciting. The people I know who are still here in 2026 are the ones running the boring version.
