That is a very very small amount of money if you want to invest in cryptos, i would suggest one thousand at least. I am going to invest in some icos next week, i have $1k budget to diversify in a few ico's that i trust. I have read a lot about them and i am convinced that i want to invest some part of my money in there. Maybe they make a huge return in a near future, maybe not... Nobody can predict the market
You can start your investment with less than 100$. Anyway better is trading you can get more profit and get it faster.
