For me, It could be a good way but we need to consider not fully trusting the system they have, so to transfer the amount to other gambling site is a good way to start all over again.
I do really believe gambling sites will try their best to somehow win back profits. What is your opinion?
What is the difference? I mean, if a gambling site can detect the profits you have made on them and they will eventually win it back then it is just the same when you are going to transfer it on another gambling site in my opinion. A gambling site would also detect how much money you will transfer therefore they are also going to put it into their bankrolls by you losing most of the time when you play, if that make sense.
