As such, what do you think will happen with Bitcoin if all the governments of the world ban it?
Then, bitcoin and other cryptocurrencies will only be used in the black market and for dark web people.
Will it collapse after the massive crackdown on every single cryptocurrency? Or will it survive?
It will collapse really hard. Surviving of it might be on a low percentage.
AFAIK, Bitcoin is largely dependent on nodes distributed geographically. The Internet is controlled by ISPs which are subject to government demands. If a global government crackdown happens, then the growth of Bitcoin and other cryptos might stale for sure.
Wait stale? Is that an adjective for food? If you're not a high profile then nobody in the government will try to supervise you. But, of course, they will eventually control the blockchain in which transaction happens. And they will find out who holds the address of a transaction in blockchain.
