Saying cryptocurrencies have technical/economic value and that they are in a bubble of inflated value can both be true.

I've seen it likened to the Dot com bubble. Sure several groundbreaking titans of the Internet were founded during that time. They are valued as major players in the world economy. But there were many more that were inflated and the sector as a whole was inflated.

Now, if you're a savvy enough investor to be able to pick the eventual winners during a bubble, you'll come out great even after the crash. But if not, then you're just gambling. And the house will eventually win.
