If you're still waiting on a manual withdrawal at this point, you're screwed. The money is gone. I guess the whole "polluted assets" story was just a ploy to give the operators time to disappear.
Manual withdrawals would never be processed from such exchanges and they might even delay your manual withdrawals by months stating that there are excess number of withdrawals and they would need time to process each and every request. If they have shady intentions than they would find dozens of reasons to avoid the investors.
This indeed is a exit scam but yet many of the traders from that exchange might be looking to withdraw their funds which is hardly possible now. Such exchanges move on the funds to some other exchange or wallets without even letting the community know about it so that they could give any ponzi reason behind their exit scam. Traders from Fcoin should treat this as a lesson and should avoid going on such platforms in the coming future.
Even a simple hacking incident reason isnt really that convincing after all, just like what happened on previous exchangers that have issues on getting hacked then closed its doors.
We have seen lots but still havent resolved and those coins are lost forever or simply means those are in the pockets of its owners itself.
Even the top exchange like Binance had suffered breaches too so i dont see a point why a certain person would tend to make use of unheard or unknown
exchangers in the market.
