Submitted title was "Finblox (YC Alum) the next crypto domino to fall?" but as far as I can tell, Finblox is not a YC company, so I've taken that bit out.

I say that because Finblox isn't in the YC list I have access to, and YC isn't in Finblox's list of investors here: https://finblox.com/about#full-investors.
