Still no one knows why I cant deposit or withdraw on Poloniex?
If Poloniex doesnt work, where else can I sell my BCN?

Advice appreciated

I believe they are connected. When trying to login to the Bitconnect site, the BitconnectX splash screen also came up.
Bitconnect is now offering to let you buy BitconnectX tokens with your Bitconnect (BCC) token at the value of $150 per BCC token.

This indicates to me that they are closely linked.

After what has happened with Bitconnect, I would advise extreme caution with BitconnectX.

My opinion...

Corrections happen in all markets all the time, not just in Crypto markets.
As others have already mentioned, this is simply a correction, and it will start going up again, maybe not today, maybe not tomorrow, but in the short term we will see it going up again.
We will all soon forget about this correction, until the next time, then everyone will panic again, and ask if that decline will continue.

Human nature.

Keep calm, and remember the last correction we had was not that bad, in hindsight, as it felt at the time
