Then when there is sites give the option to invest without KYC verification no will go such option.
But mostly, the exchanges require traders to do KYC. I only know Binance which don't need to do KYC, but if you do KYC, your limit will be bigger than the traders who don't complete KYC. Yes, we want to play gambling on the gambling website which doesn't require KYC because we don't want to send any document to them. Perhaps, gambling website which doesn't have to complete KYC will have a big member who will play gambling, and I am sure that they will stay on that site and have fun.
We don't need to risk our identity sending personal documents for kyc requirements, and as you wanted gambling for fun and lucky wins it should be done privately. I wonder why it came up on their mind seeking every users identity to be transparent with them. Maybe this kind of implementation was too strict and I don't think the people didn't seem to appreciate this. They're just pushing away customers, because most of them preferred to be anonymous instead of revealing their identity.
