Just FYI crypto-currency is not the global currency of the future so I partially agree with this post.
Nevertheless I still like Bitcoin et al. But McAfee's manparts are in serious trouble.
What I cannot agree with is that the intrinsic value is zero. The ability to instantly send money digitally at the push of a button in an electronic era has the potential to make a serious dent in the financial industry with several trillions at stake. But only the righteous will thrive.
Maybe yes or maybe no, no one knows but most the coins that will go down to zero are the one that was already bring dumped by everyone. Bitcoin was made to change what was the banks and governments doing in our fiat currency. So it could be very difficult to justify if cryptocurrency will gonna perish without a fight. Most developers are working hard to develop the best crypto in history and on the coming future.
