I bet on many matches everyday.
For me this is the way to go
WHY ?
that is easy....because i can earn more money.

I prefer to have a smaller yield and more profit
as a high yield and smaller profit.

one example.

bettor A: yield 25% - profit 50 units
bettor B: yield 15% - profit 100 units

soo...answer..yourself which one you would
prefer to be ?
I think all people would choose the bettor who
can earn more money even with a smaller yield
because in the end the profit is what talks :)
