Daily trading is the answer, at least you need courage and patience
by looking for a profit of 10% per day, within one month your assets will be 50 ETH, if you can trade daily without any mistakes
but we know that trading is not easy, requires skill and thoroughness so as not to make a wrong decision
Daily trading is the good way that I think about. Compared to buying pre-sale ICOs, it's not that easy to do, but it's easier to choose. You will have to learn some basics on buying and selling on the floor. But do not worry, it will not be too hard.
