To gain profits when crypto is dropping is very simple and common as well, i have two patterns in which we can use to determine for this.
1. You can be profitable as the market is falling and then you're taking advantage of buying the dip and investing, then you hold for the time being before it start to rise.
2. You can also be profitable when the market is falling by being a trader, whereby all you do is in taking short positions, but you must have seen it that the market is with all indication to be going down than rising.
Lets be sincere here the two patterns you mentioned here are not simple at all. holding a volatile asset requires a lot of discipline and commitment. Something that is learnt the same way we learn other skills and the same goes for trading. If professional traders record losses how much more a beginner. Trading requires training too, even if we choose to trade with bots we still need to understand the basics so we can detect/spot error in any setup made by the bot. Nothing is really simple if we must tell ourselves the truth.
