It is possible but it is not easy, depending on the market the failure rate of traders can be between 80% to 99%...
No one can deny the fact that in a bull market this percentage may be higher than in a bear market. And everyone who has experienced at least one cycle remembers how in order to get a profit, you just had to buy some kind of coin, the price of which was higher literally the next day. But with the onset of a bearish cycle, all the profit received was usually lost.
Trading results are better during the bull season but a trader must have to find a way despite the difficult times like we have these days. Either it was just 3-5% earnings per day still big enough to survive. Otherwise, we push to change our job to become a holder.
We could say it was not a good time for traders but I see some people are still enjoying this and still earning, and they have no complaints about it.
For a trader, actually the bullish season and the bearish season are not much different, because they take advantage of every moment indicated by price movements. Also often they use a relatively shorter time frame.
Talking about income for a trader, it will also talk about the capital they spend to start trading. The capital they have is important because it will make it easier to determine the profit they set. I mean minimal capital doesn't make sense if you target big profits. Of course this must also be done by an experienced trader.
