I prefer spot trading because it is much safer, although I have to have a lot of money to get enough returns, like 1%-5%. And when the market reverses, my total holdings will not be reduced, I can have the opportunity the next day to sell when the market recovers, I feel much more comfortable with this trade. Sorry for going a bit off topic but maybe you understand what I mean.
You may not see them now, or there are almost no signs that they are coming but trust me, they are always there, so why are you guys not doing the best as you can to stay safe? Just in case you already know this. Spot trading will now become riskier if you will use more money but the only thing is, that like you said, your positions are not auto-liquidated. Although they can too if you use a stop loss.
