I have this pretty typical problem: when spot prices go up, I want to cash out immediately, but end up selling too early; when contracts retrace, I hold on stubbornly, and in the end, either I’m slow to stop loss or I get wiped out completely. Later I realized it’s not that I don’t understand the market, but that my position size is too “greedy.”

One straightforward way: first set a maximum loss you can tolerate, then decide how much to buy. For example, I only allow a maximum loss of 1% of my account on this trade. Whether it’s spot or futures, calculate the position size based on that, and accept it when reached—don’t add to the position at the last minute. Basically, guessing the right direction isn’t hard; the hard part is controlling each loss to be a small noise.

Recently, the community has been arguing about privacy coins, coin mixing, and regulatory boundaries… which makes me want to write strict rules: avoid touching things I can’t clearly explain, especially those that might “turn sour” overnight. Be more cautious.
