It's all good, but you can't really win anything with these games. Here, it's like in other sports. The bigger the tournament, the more unrealistic for the bettors to make $$
For example. Finals, semi-finals of the UEFA champions league, FIFA world CUP.
At such matches nobody wins. Simple. It's just the excitement and entertainment at this level
In Dota International same..
Then why don't you just ignore it and just bet on predictable tournaments/events? Problem solved.
Well, I wrote. Mega popular tournaments are unpredictable. Too evenly matched. The best is the medium games... But here we have too little regulation and too much risk of dishonesty...
