It is true that for what is the salary and the monthly expenses the volatility of the market is something to consider among the disadvantages, although as an investment it can be taken in slightly longer terms, for example, even when the price of Bitcoín is almost 40 % below the price it reached in June of this year, we still have forecasts that point to a rise in its value by 2020.

Although I am not very given to the bets, I feel like McAfee's forecasts are correct :)
