That's true but yobit is the only exchange where you can have fun trading 99% coins and have some profit. You have to know 99% wallet goes to mainteance mode after 1 month, so trade on that period time and have fun.
Better yobit then c-cex where you have to "vote", or nova where they ask 0,3 btc for list coin, or any underground exchange with 0 volume.
Also bittrex is going to become a scam exchange, they don't add new coin before month of source stability and source code review.
But they add coins like DAO without any test or stability, and then.....remember dao drama.
Most exchange do what they want, they have the roundtable. Some add only coins where they think they can achieve volume and profit, some add small crypto asking 0.1 like yobit, some ask 0.3 like nova, some ask you to vote etc etc.
You have no idea on what you're talking about:
1. As far as I know, Bittrex done nothing wrong so far.
2. Paying to exchanges to list a coin is just not right. Why? Because pretty much every sh*tcoin has the chance to be listed.
3. Listing 'coins' like the DAO is normal as the exchanges are expecting volume and this is how they pay their bills. You can't blame them for that. And, btw, I remember the DAO drama very well (what an irony...)...
