Well, there are times when one, as a casino player, learns that every time there is a casino bonus, it is somewhat dangerous to take it, because there are certain conditions that do not favor the player, perhaps a very large wager, I have seen casinos that are wagers of 30x and legally it seems to me that it is too much, so it is difficult to reach that wager and with profits, so sometimes I see bonuses as a double-edged sword, usually when playing in a casino one must take into account who wants to have fun, but if he wants to win or win, I do not recommend it under any circumstances, because the people who chase profits end up losing.
I also think that bonus programs are calculated by devs solely in order to get the maximum profit. The bonus is just part of the funds that casinos also receive from players.
Here, the marketing strategy provides for a time interval with a peak in the receipt of money from players due to their excitement and their personal assessment of the attractiveness of the bonus. Moreover, the process develops and ends quite quickly.
And based on the results of the analysis of the receipt of money, devs decide whether to continue offering the players the following and similar bonus program.
