I have friend borrow my btc and never return earlier than Dec 2016. And for the price of btc now, it does not look like I have hope that my btc will be returned ...

If that friend owes me 0.1 BTC then he has to pay me 0.1 BTC back. It's not that hard to earn it back though, there are enough opportunities.

if you had lent your friend a pineapple, he would not give back a coconut

First you have to make sure he remembers the private key, then you need to make sure he remembers you.

I would be on him like butter on bread. Seriously? I will move in with him and monitor my investment. Lol

I'd have to subject him to slave labour until he had repaid my debts, send him down to mines to dig for diamonds and rubees until he has sufficiently repaid my debt plus interest, plus additional costs for the mental distress I endured for not having the 0.1BTC.

But more likely, I'd forget about ever reclaiming that money as it is obviously long gone. At least ask them when they'll pay it back, right now 0.1 is about $1100, so they can just pay you $1100 cash.

I am always following 2 types of dealing : 1. USD value based 2. Fixed BTC amount based. So, there will be no problem for me to  get paid or to pay any loan or pending amounts. It is mandatory to clear terms well in advance how are dealing after getting into cryptos. I am running few freelancing jobs and I have different payment terms.

If the case of bitcoin was falling down from $20k to $10k from 2017 December to January 2018. What a person can do if he owes 0.1 BTC from those times. So, how the initial terms agreed is more important for repayments.

...he is still owing you 0.1 BTC. The lending has been done in BTC and in BTC it must be returned. Unless specified otherwise. If the friend was in need of cash, why would the lending not have happened in FIAT?

It is better to pay a creditor than give to a friend.

True. The correct statement! Meanwhile, I would remind my friend about it, and I will not feel confused. He must return 0.1 BTC at least (if he is a true friend) or even more with%% if he is just a buddy.

If your friend owes you that then it is your right to ask them to pay for it,
But I really doubt that your friend would pay you with Bitcoin maybe your friend would just pay you with Fiat ,
But with the price of what he/she borrowed .

No shy and no compromise with bitcoin and  crypto currency so you are saying very right that it is too much long time period so remainder is needed for it, maybe he is not aware of it or maybe he forgot about it. So according to me bitcoin has become very high in price since 2016 and it is not good to hold peoples bitcoin for that long time, it is your right to remain him/ her about your bitcoin.
