Ok neither of these are easy but as a long term strategy to do think its best to day trade and try and get 1-2% a day or invest in a couple of coins and try and get 20% over a month
Profits depends on risk, for exemple you can either choose to lend your bitcoins on an exchange for a 10% annual rate but a pretty low risk (considering the exchange doesn't get hacked/scam), or you can choose to scalp/day trade, high risk high reward!
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 don’t 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.
Statistics exist and it says that only 3-5% of traders that deal with cryptocurrencies get their profits regularly and reach success. Therefore, the main thing here is not to think of how much you can make and which of the strategies will be the best one for you. The main idea is to create a strategy where you will not lose or at least make these possible losses as small as possible.
It is true that very few traders succeed in the long run, so it's essential to distinguish yourself with your own strategy and to have a very good risk management
