I would recommend you to make a little bit of research before investing in any token/coin due to the fact that you should always follow news of the project, sometimes the project may looks like it is going to be necessary for the future but finally it may become a scam.

In order to reduce risks you should divide your portfolio, for example 50% bitcoin other 30-40% in ETH, EOS, NEM, XRP, XMR, LTC etc. and the rest 10-20% in risky tokens/coins.
