If I understand correctly, JD originally suspended operations because of legal concerns about dealing with a cryptocurrency that can be directly sold or purchased with US dollars. CLAM doesn't (yet) have that "problem."

If my understanding is correct, JD is unlikely to accept BTC ever again, however, if the regulatory environment changes (or an exchange starts trading CLAM/USD), resulting in CLAM being similarly verboten, it may have to close (or at least cease using CLAM).
