How to think about position sizing on memecoins

Most beginners obsess over which coin to buy and almost ignore how much to buy — yet sizing is what actually determines survival. In a space where coins routinely go to zero, correct position sizing is the difference between a small recoverable loss and a blown-up account. Here is how to think about it.

Start from "it can go to zero"

The foundational assumption for memecoin sizing is that any single position can go to −100%. Size every trade so that this outcome is annoying, not account-ending. If a coin going to zero would seriously hurt, your size is too big.

Risk a small fixed fraction

Cap the amount you can lose on any single trade to a small, fixed fraction of your account (many traders use 1–3%). Fixed fractional sizing keeps any one loss small and makes your results consistent and learnable.

Size to the pool, not just the account

Your trade should also be a small fraction of pool liquidity (well under 1%), so your own price impact does not wreck your entry and exit. On thin pools, the account-based size and the pool-based size can conflict — take the smaller.

Let conviction scale size within a cap

A cleaner setup can justify the upper end of your size range, but never blow past your cap because something "feels" certain. Nothing in memecoins is certain, and the oversized "sure thing" is the classic blow-up.

Cap correlated exposure

Several coins in the same narrative move together, so they are effectively one position. Cap total exposure to any single meta so a narrative collapse cannot take out your whole book.

Keep a fee buffer

Always retain enough SOL for priority fees and exits. A position you cannot afford to exit because you are out of SOL is a sizing failure, not just a fee oversight.

Key idea — Good sizing is your last line of defense when your safety checks miss a novel scam. It turns disasters into survivable losses.
