You wanna move 10k $ still Easy
You wanna move 100k $ need some quite bigger reason....you wanna move 10 mil $ still need very big reason for that you wanna move 1 bil $ ... need geopolitical global bigger reasons.
You can't just move money bigger money requires bigger reasons.
In order to move you need reasons and big money requires geopolitical volatility and changes often they not pleasent but how you move big money or how you take big money and wealth so you need geopolitical reasons.
Specially when goverment offialials circles want to put state money in their pockets.
Because the banks are in need of reasons and they have the secrecy that needs to be known to them. But moving that amount of money with Bitcoin won't be required any question. Because we're all our own banks and these transfers won't be stopped as long as you do it with your few clicks away without having to fill any kind of form for you to have it done. Even the fees, they're not that much if you do this transaction in Bitcoin. No need for clearing periods or what not as long as the network confirms it, the job gets done.
