I understand and i might have to do that, 100 BTC loan is huge, i mean i wish i could do this by USD and just have a system where they get the $125 every month, but i am still thinking on a solution.
Can you explain why doing this in USD isn't an option? Also, how thin are your margins here? Can you
comfortably afford $125 per month because sure as shit
something unexpected is going to come up over the next 10 months and if you can only barely afford the $125 then you're setting yourself (and your new lender) up for further default.
$1300 isn't a huge amount and that's going to be part of your problem here. It's the kind of amount that people only seek from strangers when they've exhausted all other options - friends, family, credit cards, personal loans, crappy sub-prime loans, selling stuff, etc.
