I don't know how Bitcoiners will react. But I know that Monero cypherpunks prepare for that exact threat.

If your life or freedom is on the line you better rely on Monero than on BTC. And as time passes on and BTC becomes less attractive as an investment people will start to seek shelter in Monero.

Privacy for rich people no matter if in USD or BTC in today's world is priceless. 

 For sure! Those tax heavens are getting harder and harder to hide money in their banks.
