I believe it is 55 more or less btc mate and not 60+? Correct me if I'm wrong but that is how my computation says about your photo.
55 is still a huge amount of btc . 1 year later the price of btc pump but i doubt if he have some btc left because he was also a big bettor . he is lucky if he decide to kept his btc a year or more for savings . big bankroll
If ever the owner was able to save that 55btc upto 2017 he's maybe retired now and just enjoying his life or the other way around if he keeps betting those days, maybe the casinos or House already upgrade their websites now wherein they will be the one who always win, at that time when owners photo win, BTC werent that high they possibly didn't consider winning at all times but after that or 2017 ATH, many casino maybe update their system so they will find way to still win at all times.
