This guy. lel, prolly swimming in money.
Steam lvl 685, ~2000 lvl 5 badges, 3.7k games.
I cant even start to estimate how much he has spent on it.
SteamDb says $20.000 with sales discount, and god knows how much buying foil and normal cards.
If i was him i'd put some ads on my profile, he must have thousands visits a day.
