After coming back to this thread, I see that, indeed, the OP is fake. First he was talking about a quarter of a million, then:
i actually need $500k now lol.
I've been reading bullshit on forums for many years and watching people make up stories, one of the most common being supposedly having a lot of money and acting like you're dumb. Leaving aside the people who win the lottery, which statistically are almost 0, people who have a lot of money is because they have earned it. They usually are not dumb, and less waste time in the forums with ego battles when the thing can be solved in an instant:
No need for an escrow. Sign the address that you hold the ~10BTC and that's it.
But make it ~20
BTC now.
