Don't be so sure! They said that they will support bitcoin gold and in the last minute they changed their mind and did not supported the new coin. I moved my holdings to them to receive the new shares based on their initial announcement and my BTG coins got lost.

Bittrex Posted an official statement about this furthermore a lot of people here as well as blog sites also posted about this. Some sites won't spoon feed you so you will have to wait and navigate their blogs for announcements.

Deposits are closed but I'm sure you'll be credited once the market opens if not this is sufficient for scam accusations but bittrex won't stoop that low.

Anyways, You can send an email to them about this https://support.bittrex.com/hc/en-us/requests/new or at support@bittrex.com.

Why would you just send it like that? You do know that the amount you are transferring is quite big and in that case you should have checked the wallet before depositing any amount to it. They didn't send the notification but it was clearly written in the wallet list.
You can only HOPE that the Bittrex team is kind enough to credit the amount to your wallet after the suspension of wallet.
You can raise a ticket now that you have made a mistake to deposit the amount to your wallet while it was under suspension.

Was a classic pump that went viral when everything on coinmarketcap.com was very very red (BTC was dropping to $1800). It was the timing. This found CHC at the top of coinmarketcap very green. People see this. Bots see this.  People do a youtube search and come up with several pumpers.  Think there is mass community support. Don't have time to do due diligence. The crypto market had been beating people down for weeks. Come join the Armaggedon against the evil whales and market manipulators. Join the righteous HOLDERS. Perfect storm.  

Actually not so classic.  This was an "experiment", to quote the DruggedOnCoins YouTube personality. Translation: this was a new kind of pump, perhaps the first time mass deception was used during the pump, as terms like "community" and "movement" and power-to-the-people type slogans were appropriated and heavily pressed amongst colluding YouTubers, along with a come-join-the-fight mentality, along with a public buy-wall strategy, along with public shaming for retreating from the battlefield.   Using and abusing the term "masternode". At all prices the DruggedOnCoin YouTube personality was like, "Guarantee yourself at least one masternode", "Look at the supply", "there's only 100 masternodes left", "control the  market", "Korean ginseng", ect.   This was a novel way to pump a coin, 1000 units at a time.

All based on zero new development at the time (there was some development three months prior).  So, perhaps the most dishonest pump ever. The dishonesty still persists as the market tests new bottoms, trying to find the truth.  

It was probably the first time a pump team cloaked itself as "the community". Currently, the actual community is turning on the lights. As each light is turned on, you can see the pumping cockroaches scurry for additional cover.
