Really? YoBit.net has a very bad reputation for not updating their wallet. I know of several altcoins where the wallet was not updated to newer versions. People's coins were stuck on old fork (ArtByte) and no response to update the wallet. PoS coins where the exchange is staking because of bad .conf (BioBar) ... I just had a to laugh at your assessment that c-cex is 100x worse than YoBit. I'd never go business with YoBit... c-cex had some quirks when I bought BBP and transferred BTC in, but I was able to withdraw BBP out to my wallet.

With all the updates that BiblePay wallet is incurring, you're just one version away from losing all your BBP coins on the exchange.
