hitBTC is despicable. They froze my account funds for six years and I still can't log in. For over six years, no one has contacted me to resolve the issue. I've sent them countless emails, but nothing has been resolved, and no one has replied.I desperately need help from an expert.
Six years is a long time. I don't think they will reply to you or will solve your issues. That's the disadvantage of storing funds in a centralised exchange. On the other hand, HitBTC is pretty much scamming sites. They list all the shitcoins, and then all the token prices dump near zero, and there is no liquidity there to sell your shitcoins. So I believe you lost your funds forever.
From our end, we can't do much to resolve your issues. Unless you are lucky, you may not get a solution. I will advise keeping continuing email and then writing to their social media. This thread will reflect on Google search as well; if you keep writing on social media, then maybe they might care about their reputation. Comment on all of their social media posts; they are the only ones who could help you.
