As far as I can tell, it is impossible, unless you choose to be a unsuccessful online casino or betting platform, the more you grow higher every year the more attentions will be diverted to your platform, you will be forced to comply, and the users won't have a choice too.
Regulatory challenges is finally catching up, I know that many will still find some excuses for this but it is the truth, there are things the team of freebitco can't tell their users, and for someone like myself, I can see that its impossible to stay a verification free platform when running a casino or betting platform, take it or leave it.
I also joined freebitco in 2016 I think, and to say the truth, this platform was the place I earned my first ever set of bitcoin Satoshi through their Faucet, and the Satoshi (I choose to call it Satoshi because what I earned wasn't up to one bitcoin) I earned from their Faucet served as a gateway into crypto for me, I started trading on poloniex (then the biggest crypto exchange in the world) with those sats and was able to grow it to a really nice amount, disregarding the fact that I later lost it all to scam out of my own negligence and ignorance, I was pretty new to crypto then, so I knew little about how to identify scam when I see one.
And fast forward to this day, alot have changed, which I am certainly not surprised about any way, for it often said that one thing that is constant in life is change.
So, freebitco now a kyc compliant casino shouldnt come as a surprise to us, such changes is normal in every new industry as it gains acceptance, most especially from the government.
