Position sizing

The only risk control you fully own.

You cannot pick every winner. Nobody does. The traders who last are the ones whose losers are small. Size decides that, not stock-picking.

The 1 to 3% rule. Put 1 to 3% of your account into a single memecoin. With 10 SOL, that is 0.1 to 0.3 SOL. A rug then costs you a bad lunch, not your account.

Size to the pool too. Also keep your buy under 1 to 2% of the coin's liquidity, or your own order moves the price against you.

Never add to a loser. Averaging down on a memecoin means buying more of something that is already failing. Take the small loss and move on.

Why MemeSim starts you small. The guided first trade suggests 0.1 SOL for a reason. Learn the receipt, then the sizing, then the coins.
