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
1% profit a day on trading is realistic to be happen, if you will have a dedication, determination and passion to do it.
Just important is that don't focus in one coin only that you are going to invest in. If you maintain this you're capital will grow
for sure.
