No Hong Kong, não há problema em usar Binance c 2 c, você deve primeiro depositar na exchange para negociar dentro da exchange.

In Hong Kong, preparing to go to OTC physical stores to buy U, this method is essentially the same as offline trading, right? I saw a post yesterday saying that when buying U, there is a possibility of getting black U, and there is a risk of the platform freezing U, is that true?
I have no experience before, when buying at physical stores in Hong Kong, can I choose to receive U through a Binance platform account or a wallet address? If both methods are possible, which is better, receiving through a platform account or a wallet? Receiving through a platform account is T+1, right? The wallet has no restrictions, planning to use the Web3 wallet integrated with Binance, which I haven't activated yet, should I go activate it now?
