I would rather suggest all lenders to take his account as collateral next time and never send 1 BTC at first go.
Since he repays late every time he has no right to ask for 1 BTC at first.
Why dont he ask for half of it, repay and then ask the another half?
Thanks a lot to everyone, the whole community for your trust...
I am here to repay guys, trust me...
I won't ruin my reputation for any amount of BTC, as I love Bitcoiners and Bitcointalk, you guys are my family...
These pamperings do not work these days buddy.
