That was a very big goal for a short time, but in crypto it is possible, but not 100% sure. You can buy some coins, preferably in ICO, and then first hope that the ICO is not a scam, and second that the coins it offers will succeed and not die in massive dumping.
The chances of earning money right now with icos are terrible I know the possibility is there but in order to obtain significant profits you will need to invest a significant amount of money and I am not willing to do that when more than 90% of the coins are scams or are managed by people that have no knowledge about how they are going to accomplish what they promised.
