I am an early joiner in steem chain so not a big authority to assess how to proceed. Just appreciate my contribution attempt ...
In my opinion the main interest could come from decentralized exchanges, where, with a reasonable liquidity pool, cash-in and -out could happen at a minimum bid ask spread. An idea could be working to a liquid anchor in the stellar dex involving also the stellar foundation and advertising it strongly. It has to be well thought as nobody wants to run an anchor at loss ... it is clear that a liquid anchor in stellar dex would make it very cheap to converto to xlm, btc and eth at least. As a second benefit there could be the cash out to fiat in many countries especially in SE Asia: I know that stellar is pushing very strong for it in connection to the remittances business.
