I think the trust problem isn't your product — it's the cold start. Nobody wants to be the first one to put real money through an unknown escrow.
Maybe instead of leading with escrow, start with something lighter — like a matchmaking layer that connects people who want to do peer-to-peer crypto swaps. Build the user base around finding counterparties first, keep yourself out of the money flow initially. Once people are already using the platform to find each other, introducing escrow as an optional safety layer becomes a much easier sell.
There might be a legitimate use of crypto somewhere but there is a lot of crime and enabling of crime. In a job market where people are looking at huge stacks of resumes they will apply System 1 heuristics to eliminate people who might have bad ethics.
(Note I am probably more positive about crypto than 85% of Hacker News users!)
