Any exchange will do. Just no C-cex please!
Yeah C-cex and POS coins are a big no no

C-Cex is definitely better than Yobit. At least C-Cex keeps wallets open, and does not enter into fake "maintenance mode" to manipulate markets. And it has real responsive support, unlike Yobit. Half of markets at C-Cex have lost any relation to the real blockchain!
Regarding staking coins and C-Cex

Well, you know, at least that provides some liquidity for some markets

I disagree. I would trust yobit over C-cex anyday.
