Yeah that's pants. We were messing with tokens on chain back in 2014/15 and that service could surely have been built on BTC coloured coins, these days I'd say liquid would be the best bet. It's about the only decent project that's not out to destroy the central banks I've seen that I really like the look of, but I ain't touching Eth.
