Crypto currency market is just beginning its development path. Due to the fact that there are no clear rules for the behavior of crypto currencies, there is a huge volatility in the market. Thanks to this confusion, investors can both win huge interest from the deposit or lose all their invested funds.  If you are afraid of losing your funds, then you need to wait for the end of the formation of the crypto currency market. So you can not get excess profits in a short period of time, but you will be able to accurately analyze one or another crypto currency (as now the fiat currencies).
