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
None of them i think. Because both side have are too much complicated thing. Day trade is too much risk in trade. I prefer people to stay way for day trade specially which people are new in trade. And now days invest on a project is too much risk too because lot of scam projects. It's too much hard to find a good quality project. But if you find a great project which have a great team, good idea and good future i think this is the best side to choose than day trade.
Both sides have a big risk behind, it's hard to find project who can provide such good outcomes, it's takes time before learning the right system and strategy to work with your knowledge, though there's traders who already find a comfort playing with either day trade strategy or medium type of
holdings to reach 20%-30% per month, it's still depends from how good you understand the market and how you will handle taking the risk of any possibilities of losing your investment.
