The most important point is to learn the deep about crypto trading and using stop loss in every trade. I have been liquidated many times because I never used stop loss in the past. Now I am aware. Always know that every trade will not go on the right way and anytime market can be crashed. So using stop loss is a very important matter to trade crypto professionally.
Some newbies are making mistake of starting how to trade with future trading, if you want to learn how to trade it’s better you start with spot trading, you shouldn’t be in rush to make money, it’s easier to lose money in future trading compare to spot trading. If you are in rush to make money in cryptocurrency, then you Will easily lose money.
Stop lose is important but I don’t think it’s mandatory, some people don’t really like using stop lose in their trade, some people believe immediately their stop lose have been triggered in a trade, the market always bounce back, so they don’t use stop lose. But as a newbie it’s a good idea if you make use of stop lose in your trade, but also newbies should avoid future trading.
