Hell freezing over: for it to discard its nature and thus cease to be what it is. Proof of work is unacceptable. The transaction cost (monetary and emissions) is unacceptable. The transaction time is unacceptable. The behavior of exchanges is unacceptable. The lack of regulation is unacceptable. The shadow manipulation of the market by conventional financial players attracted by the lack of regulation is unacceptable. Need I go on? Fix as much of that as you can and it becomes regular finance with extra steps, and thus, pointless.
