So far, I have only found a few objective assessments derived from what was experienced and of course they must be tried one by one, so as not to give rise to various inaccurate data. you can see it here, this thread is pretty good as a gambling assessment site.
https://bitcointalk.org/index.php?topic=5335097.0Thank you for the link haidil, I find this thread and this reviews from GamblingBro very interesting and very reliable, this guy seems to really be a professional gambler like what he claims. I note he gave his best rate to Stake, then it shows he's not a random noob or referral hooker.
you're welcome if it helps you, that's great and certainly looks professional from the way he gives reviews and sacrifices his money to try every best site on this forum. It's much better I've ever found where there is a professional gambler on this forum by giving us a good perspective before gambling on any of the sites. Right now it seemed like he was still in the ongoing appraisal stage.
Let's see how much it costs him in total and find out the difference in his losses. But that is not the important point, rather he is not donated to it, doing so on the basis of increasing the experience of all gambling sites.
The assessment has been very objective so far.
