The matter of whether he still holds those bitcoins until the 2018 bull run, if he holds them it's a fortune enough for him to have a pretty decent life, but how many people can afford it? belief in bitcoin at that time???

Where did he mention that he is loser or something like that? I have seen him saying that he didn't regret it because he found it more suitable at that time to feed his family.The other user who got 10k Bitcoins also sold it for normal profit only.They didn't know it will turn this big so there is little sad feeling about it but don't think he's loser as he used it for the actual purpose.

I've only heard about the story about the guy who bought two pizzas paying 10,000 Bitcoins ever since I came to know about Bitcoin, even the second story you mentioned is new to me because I've never heard about it. I do remember the time when I first came to know about Bitcoin, and since the price wasn't that high, people didn't really care much about how many Bitcoins they have and they were always eager to find a place where they can spend Bitcoins.

I remember I managed to earn about 0.5 Bitcoin only by doing micro tasks from websites here and there, I know that the value of 0.5 Bitcoin wasn't so high at that time but imagine having 0.5 Bitcoin right now or when the price went up to $69k, I didn't manage to keep any of it though but spent it all back then and I regret that all the time.
