Everything about investment is all about risk, the question that comes in is "are you ready to make the decision to take the risk." Investing with the top crypto currencies like BTC, ETH, LTC, DOGE etc are all under decision making. If you think they can give you a remarkable profit within a certain time range after all research you have made so far, then the risk will have to be taken, but if you are not satisfied with your research, no need of taking the risk, cause the trust you have on it is not good enough.
