Unfortunately, everyone is a LONG way off from just being able to send in BTC (or any other crypto) directly to an escrow company as the down payment (if you are trying to obtain a loan).   The big jump that we were just able to make was the ability to sell the BTC and use it for down payment funds without having to leave the USD sitting in your bank for 2 monthly statements (which was generally required) for any conventional, FHA, or VA loan.  

I know that sounds like a tiny step, but anyone who has purchased a home in the USA in the past few years can vouch for the typical difficulty of going through the Underwriting process.
