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
As a day trader, I can easily say that to get 1-2% in a day is easier than 20-30% per month. Because to gain 1% in a day you need a strategy that you can use every day. You don't need any fundamentals and market conditions. just hit and run.
