I think that's the only purpose of jumping from one online casino to another so that we can find where the best is and more suitable for us. There are players/gamblers who don't like sports betting and casinos combined in one site while there are others who find this better because they both play those types of games.
Then, there are gamblers who are also looking for a game that they cannot find in other casinos. While others are more centered on finding the best UI and reputation.
There are also times in sports betting when the other sports bookie has a better offer than another so I guess convenience-wise and profit-wise choices will be made.
If it only one or two accounts it still very easy to achieve this, but when we have to use lots of accounts, we'll just spend more money.
In a period of one to two years, I sure that without chasing it too much, we can get VIP level benefits which can provide a small weekly or monthly bonus.
I personally use several accounts on different sites just to see what the odds are on each site and to be able to ensure that the option I bet on really has a big chance of winning.
There is no other goal other than to take other sites into consideration at every opportunity that arises and when I feel comfortable and even have been playing on one site for quite a long time, that is the only one that I always willing to put aside some money to deposit and play or bet on.
But out there there are also some gamblers who use several accounts at different casinos to be able to get more bonuses considering that each casino always provides bonus promotions almost every month.
But in my opinion promotional bonuses are just for fun and will not be able to provide more tempting benefits unless they are bonuses with certain conditions such as deposit bonuses.
