I strongly believe bitcoin is not a bubble and i can't see it going down.. if they are a bubble how would they go down? i can't really see that scenario.. but many expert do believe so.. but i can't really see crypto going down. I even believe there will be integration with the current financial fiats.
Bubble is something which does exist for sometime and it bursts when it becomes bigger. Bitcoin is rising, it may fall or it may rise, opinions differ according to each and every person from his/her point of view. If a single person says bitcoin is a bubble won't change any fact. If it's a bubble it's a bubble, if it's not then it's not. A single user's opinion doesn't add much. And this is just a waste of time asking whether bitcoin is a bubble or not.
