How to size a memecoin position

Why this matters

You will be wrong often in memecoins. Sizing decides whether being wrong costs you a small, recoverable amount or ends your run. It is the core of survival.

Step by step

1. Pick a risk-per-trade rule. Decide a small fixed fraction of your account to risk per trade (many traders use 1–3%). This caps the damage from any single zero.
2. Account for total loss. For memecoins, assume the realistic downside is −100%. Size so that this outcome is annoying, not account-ending.
3. Match size to pool depth. Keep your trade a small fraction of pool liquidity (e.g. well under 1%) so your own price impact does not wreck your entry and exit.
4. Scale with conviction, within limits. A cleaner setup can justify the upper end of your size range — but never blow past your cap because something "feels" certain. Nothing here is.
5. Cap correlated exposure. Several coins in the same narrative move together. Limit total exposure to a meta so one narrative collapse does not hit your whole book.
6. Keep a fee buffer. Always retain enough SOL for priority fees and exits. Running dry means you cannot sell when you need to.

Common mistakes to avoid

• Going "all in" on a single high-conviction coin.
• Sizing as if a −100% outcome is impossible.
• Trading a size that is a large fraction of the pool.
• Stacking many coins of the same narrative without an exposure cap.
• Leaving no SOL for fees and getting stuck unable to exit.

Quick checklist

• ☐ Fixed risk-per-trade rule set
• ☐ Sized to survive a −100% outcome
• ☐ Trade size small vs pool depth
• ☐ Conviction scaling within a hard cap
• ☐ Correlated/narrative exposure limited
• ☐ SOL fee buffer retained
