Why bother listing a coin only to turn around and delist the coin weeks later? You can't honestly tell me that it takes huge amounts of processing power or server space to keep a wallet up for coins.
Some coins are small but may have a vibrant or active community that is slowly growing as word of the coin spreads, but by putting this "delist threat" on the coin, I believe you completely deflate/defeat any chance of that coin's support growing. What new investor is going to want to buy in to a coin that has that warning on it, even if the coin is legitimate, with a dedicated core community and an active dev... Why would they? So from the start if they aren't meeting your volume expectations (meaning making you as much profit as possible), they are doomed. Who cares if the coin has potential or could continue to grow. They aren't making you immediate profit so you drop them. It's like Bittrex is fully promoting the PND coins, leeching as much profit as possible, while most traders get burnt, then dumping the coin entirely from the exchange.
It is beyond frustrating, and it seriously makes me wonder if Bittrex has been involved from the beginning with the ever growing number of scam/PND coins that disappear as quickly as they appear on the exchange.
And now you put a 50k satoshi minimum to buy or sell a coin?!? How are smaller coins ever expected to grow? I looked at my portfolio today, and this completely makes it impossible to buy/sell over half the coins in my wallet. Coins that I was easily trading a few days earlier, are now just stuck in limbo. I can't sell out what I have bought, and I can't buy more unless I meet your excessively high minimum order requirements (and I can't increase my coin amount by trading in the gap between buys/sells, which is really damned lame).
Bittrex seems to be making it harder and harder to want to do business with them, why should I bother? Because you add a new coin within days of it launching? Why would I buy it knowing as soon as it isn't making you money you will drop the coin. It's also now pointless, as unless I invest your specified amount, I can't get in to that coin. When I have extra 20k satoshi, I can't buy 100 of some random coin (that I might not buy otherwise) selling at 0.000002. Why not? Because it's not making Bittrex a profit.
I know this is a business and all, but come the hell on, all of those small transaction fees have to add up. Quit promoting PND shitcoins that magically disappear once they are no longer profitable to your exchange, or have fleeced half your users from their coin. Quit adding things like minimum buy and sell amounts that prevent your users from being able to freely trade coins in their wallet.
And most of all quit acting like this is about the user's experience, when we all know this all has to do with one thing. Bittrex increasing Bittrex's profits.
