join a good ico project, that's all I have done so far. maybe buy a coin whose price is cheap, then hold for as long as possible, and sold at the time when price goes up can also increase profits.
this is the thing that you may have to apply a lot of patience so while you are making and thinking what does are the thing that are able to be with is try to check what would be the best for it is really important that you are able to take some time on this than wasting on some useless project.
