If the value of DRK drops during the term of the loan(collateral < 100110%) I'll submit additional collateral back up to 125%150%. But you'll have to send me a PM or write here and explicitly ask for additional collateral, and I'll send it in 24 hours!
Only trusted members + Escrow! Preferably 2-of-3 escrow. If possible, suggest at least two escrow providers and I'll pick one.
