You have some bitcoins? I guess you may know that 1 bitcoin costs more than 60K USD and if you sell not only one but some of them and get deposit on your bank account, I guess you may receive call from your bank and get asked about who paid you that amount of money and why. If I were you, I would be more careful and would go with Binance, Coinbase or with any other reputable exchange and submit KYC. If the reason behind non-KYC is personal that you don't want to state there, then my suggestion is to not exchange all the money immediately or you'll turn red alarm on yourself from the bank/government.
