I do not believe in the term bubble to mean one big rise, and then pop it is all over. There are many recognized bubbles in traditional markets. The real estate is one, and I am even investing a small amount into a real estate project (blockchain but also real life) so that is two bubbles together I guess. There is nothing wrong with a market that goes up and bursts, and then goes back up again for a new bubble. When did bubbles suddenly become a bad thing?
