1. India crypto ban is going on for years now 2. China crypto ban has become a joke now, they banned / un banned crypto like 50 times already.
I think what she meant is the very nature of BTC or crypto that even if Govt bans, its just unstoppable. You can still hold it in your wallet and do transactions.
Yes, till you buy your crypto with fiat currency, govt. can trace you, what if you mine / stake or get it by p2p somehow, can govt stop? No they just can't.
At the end, govt should put effort to understand it and regulated instead going completely against it. Its a new tech giving rise to new financial authority that is decentralised and may look scary in the beginning like any other tech for that matter.
And we have seen this happening again and again, Machines will take jobs, AI will take jobs and what not. Let's accept it and build a better future.
