Binance Smart Chain has officially been added to THORChain. So, you can now bridge over to BSC via LEOFinance BHIVE / BHBD or you could use Splinterlands to bridge over to BSC (there is a lot of liquidity on SPS and DEC on Hive Engine).. you pay fees though... they get you coming and going. You can then trade for BNB or BUSD on Pancake swap and head over to THORChain to trade for native BTC. You can go backwards when the time is right and trade your BTC to BNB on the smart chain and head back into Hive that way. Liquidity is not horrible and you maintain custody the whole time (questionable on Hive.engine and Binance Smart Chain... half custody anyway). Anyway, the option to go from Hive to native BTC without using centralized exchanges is there now... although the path is still kind of rough.
