Perhaps scalping, one of the activities that can bring 1% -2% per day. Or trading without shorts, you can also with shorts if you are experienced.
In any case, for all these activities you need experience and knowledge. How to earn 20% per month from my income without any particular risks, I dont know, all the options I know are quite risky.
Income of 20% - 30% per month is a fairly large amount. As a rule, such incomes, especially in the crypto sector, are fraught with high risks,
which means that in some of the months you can lose a significant amount of money from already earned ones.
I like the earnings of 1% -2% per day more, because every day the amount will increase and increase.
