I pay attention to range of choice of games because casino is mostly fun for me. Also the coins which are available at casino are important, I hold some of Futurocions so I decided to use them on Futurobet.
I decided to register an account on FuturoBet just to get rid of my FTOs to be honest ;p
For me, what matters the most is the consumer satisfaction that can keep a user stick on the site and gambler for long. In addition, instant withdrawal are also something that is appreciated by the gambler. That being said, you should look for the site that provide great ease and opportunity for the gambler to make money. It is absurd to gamble on the kind of site that gives tough time.
I have to disagree a bit. The overall satisfaction can be oftenly exaggerated by positive experience someone had with a casino, for example by winning streak, even though such platform can be shitty. I'm not saying that consumer satisfaction is not important, all in all it is something that makes you coming back, but it's very subjective and it truly can upset the real quality of services provided by an online casino. There are many factors in this thread which should be very important for gambler and taking all things into account is the key. But hey! All in all - it's always someone's decision and our advices might not be as important as simple enjoyment.
