I have couple of friends who are doing crypto trading professionally. They say that day trading is so tough right now and the price is just so unpredictable so you can lose a lot of your assets, if you trade daily. But, the opposite situation is with HODL strategy. Cryptoccurency market slowly develops and its capitalization right now fluctuates in the range around $300 billion, and capitalization has skyrocketed from the last year. Thus we can make an assumption, if cryptocurrencies solve some big problems all around the world, then definitely the price will go up because more people in the future will be using cryptocurrencies. 

Thus I advice you to stick to some interesting ICOs that are available on the market. For example I've invested recently into perspective ICO which is called Cryptics. These guys have created a platform that is capable of predicting the price of different cryptocurrency assets with high accuracy rate up to 70%. Currently it can be used for free, and there's no such a tool on the market which can analyze crypto assets so well. This technology definitely solves some traders' pains, thus it can easily grow in price in near future.
