Bittrex is pretty much mainstream within the altcoin trading game so it is pretty much understandable that they take-off the old coins.
I like
YoBit because they keep the coins on their exchanges and they don't have any issues when/if the developer hasn't been online in 4 months.
I don't think that Richie will have any coins on his mainstream exchange if he continues with the application high-fee and booting users. For the money...it just isn't worth it.
Unless Richie sells Bittrex there isn't a future for it besides it being a high-fee exchange.
A good coin platform doesn't need Bittrex at all lol.
