I don't think openledger's FIAT offerings are in the picture here, we're talking about new FIAT onramps through lykke not OL.
First importantly, the only on/off ramp that will open there is against BTS once we have legal clarity for BTS (hint: read the worker proposal: http://www.bitshares.foundation/worker/budget/2018-02-legal-council-bts) ... the plan is to go further and request legal clarity for bitassets for currencies like bitUSD, bitCNY etc ..
I'd think that the bitassets would be far less questionable than BTS itself, because there is less of the mixed up equity terminology surrounding them.
Looks good, though I'm not entirely fond of pandering solely to Bittrex. That said, a successful no-action intent from the SEC would probably be massively beneficial for future exchange addition. Idk if we should be pushing BTS to centralized exchanges as much as we should be pushing bitassets - for one bitassets lock up collateral, and another non-BTS assets held by centralized exchanges pose no voting threat (exchanges voting with BTS, unless bitAssets count towards polls?)..
