Since you are a newbie and you're claiming to have 7 bitcoins right now,do you mind showing us the proof anyway ?
1.Sign a message from the address you're holding coins at,if you don't know how to do that,I will help you.
2.This will make sure you're serious about the business and not behind hijacking collaterals.
Edit : If this post is ignored,I would not recommend anyone giving your collateral to him.Please use Escrow.
I'll ignore you, you just want to count posts for camigin don't worry bruh I won't give you anything
