It is probably true that governments would have a hard time killing BTC by going after transactions and, harder yet, the network due to its decentralization. What if they just decide to cut it off its food supply?
What if the banks decide that their profits may be at stake? What if the banks of the major countries decide to launch a coordinated attack and close all accounts of BTC exchanges.
There was a
similar topic recently about the scenario where large world governments would want to shut down Bitcoin. See replies there (
here's my take at it), they won't succeed and effectively nothing is gonna change.
How then would new money come in to BTC and how would existing BTC holders get money out? Who would want to accept BTC at that point?
You seem to be confused, Bitcoin
is new money. And new bitcoins come from mining. And "get money out"? What do you mean, similar to people getting money out of the Euro or Dollar, or what?
Either way, I for one would be happy to accept BTC.
Could the banks even do this without a legal reason?
As if banks would care even the slightest bit about legal issues
Concerned...
Let me know if you wanna get rid of your bitcoins. I'll buy them.
