If we asked a question which was seen as on-topic (and maybe even upvoted) and it hung around on the site for a while, but did not generate an answer. Can we migrate the question to another site where it remains in scope? Or should I just cross-post and double-link?
As a concrete example, I asked a question about crypto-currency on Jun 28:

It generated a answer-comment but not quiet an answer, some upvotes, and otherwise has sat idly on cstheory. Since that time, however, a new SE site sprung up:
Where this question would remain in scope. Does it make sense to migrate the question if the OP (in this case me) agrees? Or would that be bad-practice?
