I lost 50k on this site, when I pay with small amount, everything is fine, after I transfer more to the site, all sudden they block the account (no email, no reason, uncontactable), my god, it's scam.
I've heard before with people saying that they are asked to provide a huge load of personal information, as well as where their funds are sourced by HitBTC, just to get their funds unfrozen, and their accounts unsuspended.
HitBTC has a pretty bad track record, and account suspensions are definitely not anything new to HitBTC administration.
Have you contacted their support to ask for the reason why you are suspended yet? It takes them some time to reply, but make sure you keep following up with tickets if they don't resolve previous ones. You deserve your money back, and $50k is no amount to joke about.
