Hey, what would take as collateral?
Hello, altcoins will do the job

I won't accept every altcoin but most of them.
Perhaps edit the OP for a more detailed overview.
It's a good offer, so try to list the alt-coins you would accept, plus all of your conditions.

Edited OP with some more info. Listing all the altcoins would be a lot of work as I will accept almost almost every altcoin.
Interested, I'm sending you a PM.
Perfect, replied.
