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.
Stocks were one of the very good way of investing money but since the time this bitcoin has been introduced to this world, this trend is changing quite significantly. Now-a-days, people are more interested in investing their money into bitcoin and other crypto currencies other than that of investing in stocks. Investing in bitcoin is proving out to be more beneficial than that of investing in stocks.
