About the platform shared by OP which I never heard about, has anyone really used it and if yes please share how was your experience.
You can see from OP's post history that he heavily shills that site. He is most likely affiliated with it.
I have not used it, and I would recommend avoiding it. It requires that you deposit your coins to a wallet that they control, so is completely centralized and your coins are not yours. Their Terms of Service say they require full KYC, and reserve the right to freeze your account and your funds while they demand "upgraded" KYC, for any reason. And of course their Privacy Policy gives them the right to share all your data with anyone they want.
So pretty much all the worst parts of a centralized exchange.
