For myself, I chose this strategy - every month I choose a project with a cool idea, I study its background, I search for the maximum information and at the start of token sale I spend from $ 30 to $ 100. I consider this as entertainment rather than as an investment. I have investments in bitcoins and ethereum. But it can work. So already 3 times made. This month I'm researching mytimecoin. I waited when somebody starts to implement idea "spend time - get crypto" and here it is!
