new casinos, one of the ways to attract new players, began to use viptransfer, transfer of experience and turnover from another casino. Many offer good bonuses, I tried this several times, do you think it is beneficial for players, do you use this offer? Share your experience)
You mean for example a VIP rank player on Monkeytilt casino being able to transfer the rank to another stake like stake.com if that is what you mean, then it can be beneficial to the gambler but the casino will be at a loss in total wagering since that is where the casino generates their revenue from.
The casino will stop at just providing bonuses to attract players to their casino since bonuses are wagered on the same casinos it makes their income remain within, unlike VIP transfers which means casino B is inheriting the burden of casino A all based on transfer agreements.
