Bittrex follows its policies and announces possible delisting of cryptos, which would occurred only such as only"not getting more than 0.2 BTC daily trading volume over a defined one-week period."
If there is proper
announcement of delisting and
allowing appropriate time (of maintaining the very crypto wallets) for you to withdraw you coins, there is nothing wrong for Bittrex to do just like that, based on its policies. If there is enough community and trading support, the trading will maintain and the delist warning would have been cancelled. One example is the UFO coins.
https://bitcointalksearch.org/topic/m.11611257I did once suffered from not getting cryptocoins transferred to my wallets from Bittrex for hours; it turns out the cause was that the blockchains of the crypto got stuck. ( Again, see this and subsequent pages,
https://bitcointalk.org/index.php?topic=844754.220 )
Certainly, it is a shame that a crypto got delisted within 1-3 months of listing at the Bittrex. Would you want Bittrex to keep those shit coins there to give enough time for the Pump-and-Dumper to do the dead-cat-bounce to victimized more innoncent Cryptotrader?
Thinking you can Dump it at a profit when A crpto gets listed at Bittrex? I bet you will think three times to even to do that. One example is Aricoin, which shittily dropped to nearly in half even before listing at
Bittrex and Cryptsy.
https://www.cryptsy.com/markets/view/ARI_BTC It is the practice of listing and pump-and-dumpering that is scamming, not the coin and the dev which are the issues unless the dev(s) is the participant(s) himself/themselves.
Overall, my experience with Bittrex is positive.It have been the particular cryptos and lack of community supports(-and functioning blockchains) to be blamed.
I have yet to see more
substantial evidences to support your allegations.
Otherwise, this place look like "Cry Wall of all Bittrex-delisted Cryptos."
