I would live to choose best ICO's to invest as well. Few ICO's are capturing the market with their projects. Its more and more profitable when investing in a successful ICO. If you are a long term investor you can buy Altcoin if you are short term or long term investment you can buy Bitcoin. I believe that in just a few years Bitcoin and Altcoin will increase and it will be profitable for long term holders. If you prefer a cheap digital currency that has a potential for future income, you can go and look for these Ripple, Cardano, DGB and NEO.
