Your owed amount should be $330 as previously agreed. Thanks! (and please give me an ETH address to return the collateral to)
Excuse me, can i extend this loan now? I would liek to pay you 30$ as a fee for the first loan and the remaining 300$ will continue on the new loan. Is it okay? I didn't check BTC price yesterday, I just woke up and was quite surprised it dropped 10%, my investment is down 20% now and I don't want to get out of it right away, I hope to extend this loan and wait for a price recovery 
I will pay an extra 20$ for this extension, do you agree? Really sorry for this incident
