I choose investment give me return more than 120% from my money, I got profit about 20% from my investment and waiting more than three months to receive my profit, after joining bitcoin and altcoin investing I can earn profit with short time and can return profit without one day, if lucky I can get double profit in one week depend with bitcoin increase price.
Good for you if you found out that kind of investment, as per me, I am fine with investment which gives return of 3-10% for a short period of time, as most of the time I don't hold long term (except Bitcoin) , I usually invest at short term.
Being a good investor is not that too greedy, know what he is doing, has knowledge with the project that he is investing at, know how to check the teams' background, have a lot of patience, and know how to handle his fund well.
