And it seems so are many of the Manx banks (probably mainly IoM branches of UK banks but still).

But the cryptosphere simply has to weather hostility from the banking sector - what else did we realistically mostly expect? Cryptocurrency and blockchain technology is their kryptonite so they aren't likely to be welcoming it with open arms, much as I think it is still profitable for well-managed banks to profit with crypto just like they always have with gold. Although I won't forget the "seen a ghost" reaction when I casually wandered into a Commonwealth Bank branch in North Melbourne (Victoria, Australia) asking if I could exchange my wad of $100 bills for gold bullion!
