In desperate condition, i will try my best to get loan from my friends. If it becomes impossible, then i would try to sell my bitcoins but with half heart.
I think before trying to borrow money would be better if you sell your valuables can you sell, to avoid losses because of high interest when you borrow money, but I do not think that your friend will give you the loan interest?
Getting loan from a friend while you have bitcoins is not a bad thing to do, in anytime you can sell bitcoins you have and return the loan. With bitcoins in your wallet you have back up plan, that is always important to have when someone is borrowing money.
I think fiends shouldn`t take any interest, it`s friendship. If anyone borrow money with interest from a friend is not friend at all. That is my simple conclusion. Only in case if someone is borrowing money for some big business, then is someone is making money with your money then you have right for interest, cause you risk in anytime that person to lose money in that business.
It's good if you have many friends so you will not only approach one friend, the more your friends the more you have a chance to loan money and the good thing is that you do not need to pay for the interest because friends just lend you money for your friendship and not for business.
