After closed btc exchange a ICO they still have giant mines. How would chinese miners sell their coins? Is it dangerous to use vpn there?
Why should Chinese miners sell their coins?
It not illegal in China to own Bitcoin. It's not even illegal to mine coins in China! It's illegal for an exchange to operate.
Anyone in China who has Bitcoin and wishes to sell it for yuan (WTF?) should move it to an exchange that operates outside of China, sell it for USD or EUR, then exchange that USD or EUR for yuan. It's that simple...literally.
And it shouldn't be dangerous to use a VPN there, it should be encouraged!
