It was not a bonus abusing exactly. Bonus abusing is if you gamble with surebets. When I was playing them I made sure that there is no sure bet for the reason you say. will usually have 0-2.00 elsewhere the opposite (double +1.96) if you are looking for top prices elsewhere, whenever you play with a rake 1.98. something% to 0.5% ... This is not an abusing bonus, because if you make a turnover of 0 € to get the full bet of 2 €, at the end of the turnover your net profit will be somewhere at 200 € - 50 € and not 40 €.I don't know if there is a risk that your money will be eaten if they consider it an abusing bonus
Of course, if it is an asshole company, what you say will happen.
