If you have invested in it before and you made a good amount of money, since you still want to go back to it, then just do your analysis before entering the market. As long as you are holding it for a long time, I am sure you will be able to make some money from it, but don’t expect the same amount that you made the last time you invested. So instead of taking that kind of risk, and i  I won’t be getting much profit, then it’s just better if I invest my money in bitcoin and have peace of mind. I will be confident that nothing will happen to the coin that i invested in.
