I have few questions before registering:
Do they let you withdraw without problems?
What are maxbets per match?
Do they limit your maxbet if you are succesfull?
In theory, any bookmaker can put a limit on your account. I haven't read anything about it for this site.
You may want to contact the site directly to ask if there are any limits if you bet too much and too high, for example.
I think that is individual for each player and nobody on the forum can really answer the question.
