Reminiscing the days of my #csgo and gambling degeneracy on csgo lounge.
Their payout ratio was not set by a book keeper but directly reflected the total amount of money people bet on each team. So if the amount on Team A was 100% higher than on Team B and A loses, the bettors on Team B would make 200% minus a fee.
Because of this, betting against the popular teams was much more profitable than on regular betting sites. It was glorious and really fun.
I eventually stopped betting and playing csgo after I learned about #Bitcoin. I converted all my skins to keys and turned the keys to BTC with an automated Steam trading bot.
Some of the items I sold outperformed Bitcoin significantly since then haha.
