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
getting 1-2% is a lot easier than getting 20% over a month. there will be days where you'll gain more than 2% a day as there will also be days where you'll lose more than 2% a day. but getting 20% over a month means getting more gains daily than losing ones. and to gain 1-2% daily for the majority of the days over the month requires more studies, research, analysis, tips and good luck.
