Depending on the interest.
The interest will always be on BTC, unless you make a deal for a fixed price and I really doubt that you can find any lender to agree with it.
So it's easy to calculate it. If you take 1BTC and the interest for 6 months is 9% per month without compounding, you will repay 1+ the interest = 1.54BTC
Doesn't matter what price BTC will have at the time of your repayment. You will repay the same BTC if the price goes to $500k or $10.
loan bitcoin and transfer via SWIF across country?
or sent bitcoin to someone in country and get money transfer from them (paid fee service, I see some people open service sell and buy bitcoin on local ,if service available) may be better?
You probably missing something. You will not get a loan and repay it with fiat money but with BTC (or other major coins). So, how you will exchange them or move them or whatever, does not concern the lender.
