Yeah you are not responsible for it, if your friend sold his bitcoin because he was not patient one so he deserves to get lose, at very frost I think one should know that if he wants profit he will have to wait and hold their coin even at the lowest price.
People do this with everything not just crypto, buying in like its a lotto ticket that will pay off after a month or so. Thats a poor attitude with the buyer not crypto itself, that whole dynamic is part of what is showing in the price for most of this year with people who expected double easily gradually realising that crypto is just an economy of people exchanging value, not a magic trick for free money
