What would happen to Bitcoin’s value if all countries banned crypto exchanges together ? Can it survive such an action ?
That would be a chaos if it happens. There will be wide-spread panic everywhere and people would rush to have their bitcoins moved and turned into fiat. These people are the weak-holders. The only people that will be left are those who believe in the core of bitcoin. Aside the weak-holders, the other group of people who I think will vanish if countries banned crypto exchanges together are those who are constantly speculating on what the price of bitcoin will be next.
But as the numbers reduce so will its price ultimately. But is not going to happen, that is too much of a dark thought to have. Even thinking about it is sad.
At this point, everybody's now speculating about the price. So, such a scenario will have an impact on everybody. The people who'll sell aren't necessarily just the "weak-holders". It would include even those who truly believe in Bitcoin. I doubt if anybody's belief in Bitcoin is so strong he/she could just stand and do nothing while looking at his/her millions fly.
How about you? Do you believe in Bitcoin? Would you not sell if such thing happens? Do you consider yourself a weak holder?
Ultimately, however, Bitcoin will rise again. Because it doesn't die, in the first place. So, it will bounce back. I'm sure those who sell will also buy back at some point. In which case, Bitcoin would still reach reach its previous highs.
