I someone starts an exchange, or if someone wants to use a new exchange, the fear is that it is an exit scam.
Well, one way to prove it is not is to have collateral in escrow.
Or some government assurance, or some insurance company assurance.

But, that is way too expensive and difficult.
And in the cryptomarket, KYC is not that attractive.

So how can an exchange demonstrate the fact that it is trustworthy?
