I don't think stocks have a better future than cryptocurrency for sure. Take an hour to look at the development chart and you will know why i'm talking like that.
The thing I want to add in this is that everything has a time, this is undoubtedly the era of crypto currency, but yet in the stock market, there were some positive inclines (with no comparison to crypto currency). So if we want to make full advantage out of the situation than you have to strike where iron is hot. Now a days its crypto currency time, may be in the future once the crypto currency gets stable then again it will be the era of stocks.
