Would you be willing to pay it if I say yes?

After reading your post below, I guess I would only pay for the interest of the loan which is 10%.
You shoulder the charge and you already accounted it prior to transfer,so I guess this is properly done on your side.
I actually realized 5% is indeed very high especially if lending is involved. But for the fun of this, I won't mind it anymore.

By the way you can also download electrum wallet app with your mobile, I only tried android since I'm an android phone user.
