I recently did an experiment. After a huge loss on 10.11, I put $10k on OKX, and by 10.12 it turned into $37k. Then I reset it back to $10k, and now I've made about $5k. On Binance, I put in $4k or $5k, and now I've also made $5k. At the same time, I put $2k on Bitget, and now I've made around $6k, turning it into $8.4k. (All three platforms are real accounts and publicly verifiable.) The trades on all three platforms followed the same rhythm, with similar amounts. So, in non-volatile market conditions, the size of your principal isn't the most important factor in the crypto space. But when facing extreme market volatility, it really comes down to your ability to sustain with margin. The key to risk control is still position management. When playing with contracts, you must constantly take profits and reset the funds you're investing. Otherwise, there will always be one wave that wipes you out. This is a simple method to make it look like you have unlimited margin. I've been doing this for years, but many people still don't get it—they only talk about holding on stubbornly or adding more margin. Most of the time, we don't lose to the market; we lose to our own desires and greed. Slow is fast.
