I've read something about that last year, as far as i remember they were starting to develop a blockchain crypto and full government controlled , but it wil take them some time I hope :D sure would hate to say good bye to money and start getting hacked by Chinese data miners :D

it's going on for years :D

And probably you can't go wrong with silver , but I'm not a trader and never have been.

Best of luck to you :) Traders :) !
