In any market, there are never tough times for those willing to trade both sides. That being said, I don't consider myself a pro at margin trading. I have known thanks to my research and deep disgust of present financial system that crypto is the future. Back when I invested, I put in a very small amount of fiat which I was always willing to lose. I've also been lucky in the sense that I didn't time my entry into the market but even in the worst of the bear markets, I was never under water so it has always been a numbers game for me without emotions coming into play.
