its a CEX, it definitely would be asking you KYC.
if its that easy to gets users into and exchange, the government can create a lot of them like FTX to collect everyone and launch any kind of memecoins easy to mine just to get the data of those users. telegram mining especially. they only need to verify thru the KYC.
but iff you already have submitted documents, just take advantage everything you can get, you never know you may become millionaire thru it.
