OK, so that may have worked before the ban, but unless you have a way to export under the counter, I presume this route is gone after the btc transaction ban.
Well, you'd have to do an off the books / private transaction of BTC-for-CNY, but there's presumably an infinite number of ways for someone to loan / give CNY for (to the government) nothing (and in reality, BTC, etc).
And with the CNY, you can buy real goods. And with those real goods, you can export them. And with those exports, you can sell them for foreign currency.
So as long as they're running an export-oriented economy, it's going to be very hard to fundamentally stamp out crypto as an option. This mostly strikes retail traders / buyers.
But my point is any time you export some physical good, you have a transaction going under the nose of the authorities. That's where they can stop you and ask some questions on the transaction that paid for those goods.
You paid for the transaction in CNY which is perfectly legal & normal (I would assume). The volume of exports from China is crazy and investigating every single transaction is not practical.
Not even that. Although that's definitely another option!
I was thinking of two separate transactions with two separate parties: (BTC -> CNY, hidden as gift or loan) then (CNY -> goods, perfectly legal and normal).
