Bittrex: lots of BCC(Bitcoin Cash) incoming

I use Electrum for storing my BTC. I've made a new wallet and transferred all my BTCs to the new wallet. I backed up and encrypted all my wallets and deleted Electrum wallets and config files from disk to be safe.

You can get Electron Cash from http://www.electroncash.org/
If you are using Mac, here is the MD5 of the dmg file I used.
MD5 (Electron-Cash.2.9.0-macosx.dmg) = b5be1395a2be5da842a2e4267ebf3deb

I ran Electron Cash and recovered my old wallet using 12 secret words.
There was exact same amount of Bitcoin Cash before I transferred to the new wallet :)

On 9:00am PDT (August 3rd), Bittrex opened their BCC(Bitcoin Cash) wallet. As soon as I got the address of the BCC wallet, I've sent BCC from Electron Cash. Bittrex is requiring 20 confirmations! Which is really crazy, because mining is still slow. Got 13 confirmations in 11 hours. 7 confirmations left.

I think I got in the first block after the wallet was open. My transactions is in block #478598.

Here are some interesting numbers from the mined blocks:
#478598 : Output total 3,044 BCC
#478599 : Output total 111,278 BCC
#478600 : Output total 227,367 BCC
#478601 : Output total 27,294 BCC

I guess most of the Bitcoin Cash are going to Bittrex.

By comparison, 24 hour volume for BCC on Bittrex is 17,359 BTC.

Still not sure if I should dump right away when it gets 20 confirmations.
Price on Bittrex is 0.165 BTC. On HitBTC, It's 0.11 BTC .
