Trading is not an easy job, I have a couple of advice for you:
1. Do not use margin trading in Crypto its too volatile
2. Always have a risk management plan
3. Never over trade 3 small losses and 1 big profit, a month are better than losing everything.
last, if you want to buy bitcoin buy it gradually like 10 % of your capital in case the price goes lower your buyback at a cheaper price and keep repeating that.
