Taking your initial out: the recoup rule explained
The most common money rule in memecoins is to sell enough to recover your initial stake once a position has grown, then let the rest ride as a "moonbag" with no risk to your starting capital.
The maths
At a multiple m, selling a share 1/m of the position returns exactly your initial stake, before fees. At 2x you sell half, at 4x a quarter, at 10x a tenth. Fees and slippage push that share up a little, which the recoup calculator includes.
Why it helps
It turns a paper gain into a free position and removes the urge to watch every candle. The cost is that you give up part of any further upside, which is usually a fair trade for memecoins.
