I always tried to stay away from coins I do not know the source and it has always worked out for me, but yes I got lucky in a few of them.
However, I have to say it, Bittrex is such an exchange I will never trust... Actually, most of them have similar attitude...
Listing a coin and delisting them after a short period of time.... That is questionable... I have doubts on those owners..
My suggestion is that never leave any of your long term coins over this exchange...
My suggestion is to use cryptsy, coz if they add a coin, they delist it if the coin really has a corrupted wallet and no more interest at all...
I think it should be the way it is, and this way is more sincere... It is not like Bittrex, saying lets move forward we made enough money, lets delete them...
So be careful... you are warned. Most of you already know it, but for those of you dont know about it, now you know it...
I also believe Bittrex is not long term, it will be gone sometime, only dont know when, with their current operating strategy...
Although I agree with your driving points -- that there are some exchanges that appear to be arbitrary and unreasonable about their coin listing policy, I also think the position without direct contact with the exchange in question is prejudicial, arbitrary, and irresponsible especially when you are recommending that they not be used.
Remember, for the most part, it is the coin community that is driving the motion to be listed at the exchange, they are essentially petitioning the exchange to list their coin because they want to trade there; or that is the face of the argument. But in reality for most CC communities they primarily want to be listed because it often has a positive effect on the value of the coin. Sometimes, many flock to a recently added exchanges to give the impression of great excitement for the coin only for that excitement to wane to unsustainable levels on the exchange even if there were no other CC communities banging down the exchange's doors begging for inclusion and promising that their community would be far more appreciative and supportive of inclusion.
The bottom-line is neither side is perfect, however both sides could be reasonable, but for that to happen there should be dialogue. This is a reason for coin foundations and community leadership to speak the will of the people with a single voice.
As for Cryptsy, I used to love to trade there even when their rate was .25%, while poloniex was .2%, and mintpal (when it was owned by the good guys) was only .15%. I used Cryptsy because they appeared to have the most selection, and the best net deals. I say 'net deals' because I factor in the higher exchange rate, higher withdrawal fees, and the cost of my time to babysit transactions. However, when Cryptsy instituted their sliding scale that turned me away. If the fee is higher than .25 I don't trade regardless of the net deal. I discussed this problem with both sides (Cryptsy and CC community) but the community didn't substantially increase volume to warrant lower fees in Cryptsy's eyes and Cryptsy wasn't willing to grant an exception to policy waiver; as a result overall trade volume of the subject coin there has decreased dramatically.
Before you make rash decisions try to create win-win deals in this way everyone is happy or at least satisfied.
I used to get pissed at what I thought was unfair delisting practices until I reached out to the exchanges and asking why?
Cryptsy's fees are .25% for DGB trades? And, 1 DGB for withdrawals? If you have a verified account, and you place a "maker" order, you don't pay fees for that trade. I'm not sure if I misinterpreted your argument, or if we're just not on the same page here?
I don't follow CEX.io. So, I can't be 100% sure about the fact that Cryptsy has the absolute highest volume of DGB trade ... but, I'm pretty sure they do. Generally, the daily DGB volume at Cryptsy is several times the volume at other exchanges. That's a benefit to traders (buyers and sellers). Markets are - by definition - the places that put buyers and sellers together. The more buyers or sellers, the more opportunity (liquidity) for exchange. There aren't many examples of brokerage firms in digital currency (shapeshift is a good example - but there aren't many others). Most of us trade on open exchanges. Because all the exchanges have the same order precedence rules, the only issues are fees, security, and liquidity (and obviously individual bias). If a trader is churning (lots of small ping-pong bot trades), then they might strongly prefer an exchange with lower fees. But, in the end, opportunity and risk are cousins with trading and exchanges. We always pay for both. I do not like Cryptsy. That's silly. And, I don't dislike Cryptsy. That's silly too ... There's nothing to like or dislike. it's a marketplace ... it's numbers, and orders, and opportunity, and risk. I trade where I have the lowest opportunity costs and the least risk.
Eventually, I think the digital currency markets will probably have to consolidate a bit. There will be lots of pressure on U.S. exchanges (i.e. Cryptsy) in the coming year as major brokerage firms (Wall Street) come online. I think it's likely that over the next 5 years we'll see many exchanges transform into brokerage companies and large exchanges emerge (likely based on geography/national currency to deal with minor differences in regulation and currency exchange). It's easier for people in China to trade with a Chinese exchange, that's why we have different stock markets in different countries. I understand your points about using exchanges as marketing ... for the past couple of years, people have associated more exchanges with broader adoption and short term news-related price increases. But, more exchanges technically doesn't provide more liquidity or opportunity, it just fragments the marketplace. In my opinion, the best thing for DGB would be strong consolidated volumes in several national markets (euro, GBP, Yuan, USD, etc.). Regardless of where or how you trade, I hope all of you have success with your DGB trading. I'm really looking forward to the DGB exchange; I think that will have some really great opportunities associated with it.
