Basically I used Kryptono exchange to trade Scanetchain (SWC). Where I deposit good amount of SWC tokens, which are not added to my account on time, when I contacted their customer support they did not reply to me for three days. When I logged in to my account three days later, it appears that my account was locked for unusual activity even though I had 2FA in my account.
I haven't been able to activate my account yet because they asked me to do a KYC which seemed a bit risky to me. I never do KYC on such a low rated exchange and never recommend anyone. However, the Kryptono exchange doesn't seem legitimate to me in anyway.
I would recommend to all traders to avoid this exchange as its security system is not good and at present the trading volume is very low. From my real experience, don't lose your fund by depositing it on Kryptono exchange.
