Вот какая инфа есть о них на этом форуме: https://bitcointalk.org/index.php?topic=958295.0
Если коротко то за последние 2 месяца только негатив, если они даже за регистрацию не платят то и за посты долго и честно платить не будут.
Вобщем скажем дружно - нафиг нужно!

and what's the roadmap? 

So yobit start to accept ico? 

I bet that the ICO will be in C-CEX LOL

Beginning block 11,000 if you forged any block and the block height is divisible by 100 (11000, 11100, 11200, 11300, ..), you have the option to sell 1,000 wcc coins to me at 100 satoshis each. The block may or may not contain any transaction, it doesn't matter. As long as you forged a block and the block height is a multiple of 100, you can sell 1000 wcc coins to me.

Just send 1,000 wcc coins to this address: WCC-2GMD-2BWC-WKJP-3RQA9
and include a message (i prefer an unencrypted message so that i don't have to login to my wallet) containing the block number and your bitcoin address and I will send you bitcoins as my payment. allow a few hours at most maybe i'm asleep at the time you sent.

The address is my personal wcc address and my only address. The other coins that I have still in possession is not mine and will soon be given to members of the community.
