I made a thread here on the board on how my end-of-the-year Christmas bonus payment was used to buy Bitcoin instead of spending to buy new clothes as my friends and colleagues did back then.
Now I am profiting from my Bitcoin investments then and one of my colleagues is now in dear need of financial help, he needs some help, not life-threatening but money, and now I am not ready to loan him any money as long as it affects my overall Bitcoin holdings.
One thing I am going to tell you is do not lend out money you cannot giveaway to someone at this particular period, it will sometimes end in somehow.
Now if your friend needs help and you think the help is worthy of your help and at as same time you don’t want to loose your precious bitcoin, then there is one way out which is treating bitcoin as a currency it self. What I menace is lend your friend bitcoin instead of fiat. If your friend needs a $100 then send him Bitcoin equivalent like 0.0015 bitcoin and ask him to pay that bitcoin back rather than the fiat value ($100), that way you still have your bitcoin intact
