If i got lucky from the lender in just 0.18 btc loan, i can repay up to 1.74 btc.

You're going to pay back 9.67x the amount back as you were given? Normal lendees don't typically say that they'll do such things: typically, people are much more innocuous with their repayment since they actually intend to repay the loan.
