What I noticed is since few months Pinny (and other major bookies like bet365) started to open odds in the middle of the night. Like 2-4 CEST. Minor leagues or friendlies. Anyone got idea whats the reason? They used to open odds early morning before which was fine for someone (like me) valuebetting but middle of the night is just crap. Can't figure it out what was the purpose of that.
