Well not particularly. As you go on to point out, it's perfectly possible for transactions in stocks and and similar investments to take place where there are no losers. Crypto is in its infancy at the moment and broadly speaking has 2 functions; to pay for stuff, and to speculate on it itself. Hard currency is the same. The fact that someone is selling and someone is buying doesn't necessarily mean that one of those two is losing money (although it may), and if that were the case it would only be a particular problem if it was the same people losing all the time. It's like football; someone wins and someone loses. That's only a major problem if you lose too often, in which case it's likely time to get out of the game!
