I am very good at sports gambling, especially soccer. because I think soccer is quite predictable in comparison with other types of games. sports gambling is also easy to guess when you bet on some great teams. although I knew they would get a defeat, but most of them always get more wins.
About your claim that soccer is predictable game - have you tried to bet on some matched during EURO 2016?
Because I lost my every bet because Iceland was on the roll in that tournament, same with North Ireland.
It was one of the most unpredictable football tourney. Same as Copa America 2016 - Argentina lost in finals.
Sportbetting is not predictable, true it is certainly more skill or knowledge based branch of gambling, but still upsets are happening all the time.
