Investment is always a risk especially if you are talking about crypto. It was said and written hunderds of times that one should not invest more than he/she can afford to loose.
Crypto and ICOs are high risk investment because once you put money into it it is hard to control or affect what will happen than. You have to rely on the project team or the industry trend. But in most of the cases you can do nothing but stare at what is happening to your balance.
Yes risk is always there and specially in crypto trading, but without taking risk I think that it is not possible to make money from cryptos, it is important to accept the risk factors and invest money in bitcoin. I think it is also important that we should invest such amount of money in crytptos which we can afford to lose otherwise we can lose everything we have invested in cryptos.
