Looks like Bittrex is waiting for blocks to be mined before crediting BCC, unfortunate because I wanted to dump my coins there. For now Kraken is the only exchange with reliable pricing on it.
They already credited BCC to me 4 hours ago.
BCC wallet is under maintenance.
Exactly they already credited BCC to my account. But my bad luck I did not believe this, and I exchange my bitcoins to altcoin yesterday night. I just left few coins in my wallet just now I checked the same amount of BCC is credited to my account and now we can not deposit bitcoins they disable that option. I missed one opportunity to get free coins.
