Escrow terms:
Both users need to sign a message with the address holding the funds.
No signed message = no deal.
That is a joke. I don't need to sign any message. Put up or shut up.
Find an escrow. let him post the escrow address and we send our btc.
I'll even send 1st but you must pay the escrow fee in advance.
If you fulfill you side and send in your 10 btc I will reimburse you the escrow fee.
If you don't send your btc then the escrow keeps your fee for wasting his time and sends me back my 10 btc.\
Put up or shut up.
