Well, it would definitely suck for many months but I don't think I would get too depressed unless that was all I had, as in savings. I have much less than 1 BTC right now and to me that's a treasure even if it's nothing in real life but if I lose it I would feel the same way as losing a huge amount of money really. Life won't change unless it's your whole savings or bankroll. Such thing is impossible for me, and won’t happen, I won’t be a full to invest such big amount online. But, assuming it happens, first of all I will faint, when I wake up I will if it’s a dream or real life, and I will feel nervous for some days.
