A good investor should always weigh their rationality more than their emotions. Sometimes we tend to be hopeful in a cryptocurrency hoping that it will bring us a massive fortune but we should go beyond this. Is the project realistic? Would the project prosper then how long?
Asking ourselves the right questions is one step of becoming a good investor.
That's a piece of good advice if I say so myself.
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.
As for me, I don't really "invest" in any cryptocurrency right now. Most of my earnings are from joining campaigns. I'm just building my capital for now before diving into the investing/trading. Well, technically I am investing something but it isn't money, its time. And besides, before I jump into other ways of earning cryptos, I have to learn more about those.
But sometimes even if you know what you're doing you have to still have to expect the consequences. After all, 95% of these projects tend to fail and would not give you enough profit to compensate for the time, money, and effort you invested to the said projects.
The longer you are going to hold, the greater will be your amount of profits earned by selling bitcoin.
Not always the case but yeah, reasonable enough.
