Maybe storing some bitUSD at bitshares might be an option. I still try to find out how secure bitshares is from govt theft and scam. It certainly is better than centralized exchanges.
For USDT there is only spyware wallet available and the token is like banking, but bitUSD is too.
I don't know how decentralized it is, that is the main benchmark if you are worried about political risk. I have heard that they have not that many nodes and mostly in the US, so that is not that good in general.
