I opened a small account today for short-term trading, while my main account still holds a short position in Ethereum at 3360. In fact, many people do not understand the correct trading system, and they often go all in, dreaming of getting rich overnight. The cryptocurrency market is particularly harsh on such individuals; with good luck, it might happen, but can you guarantee there won't be any sudden market spikes?
A correct trading system should reduce frequent operations. If you find yourself on the wrong side, you should cut losses in a timely manner, then reduce your position and leverage to keep risk within your tolerance. It's okay to lose on one trade, you can make it back on the next one. Holding onto a losing position is a major taboo. I've seen a player in my group who opened a long position in OL coin at 0.45 and another long position in Ethereum at 3776, and they are still holding on until now. Every time they get paid, they add more money for margin. Now they can't sleep well, and they look like they've aged 10 years.
