I offer an opinion from possibly the greatest investor of all time
A comment made at the recent Berkshire Hathaway annual meeting
by Warren Buffett
..........
.. On cryptocurrencies:
“When you buy Bitcoin, you are just hoping that the next guy will pay more; it will not produce profit itself. That is not investing, that is a kind of game ... Anytime you're buying a non-productive asset, you are counting on somebody else to buy it at a higher price on a later date because that person thinks he would be able to sell it to someone else. Eventually, cryptocurrency will come to a bad ending. It has nothing to add value to it." [Buffett]
