If Revo takes too long to get added to bittrex, I believe that it's lifespan & volume will be very short lived.
I don't think so. Minerals was successful partly because, it got listed on bittrex after POW is over and till then considerable amount of coins from shaky hands exchanged and when it listed on -trex price was way high from c-cex.
On the other hand, on the Bittrex, Poloniex the coins' prices manipulated by bots and whales, wich may cause very short coin lives and loses in many times... See Trustplus, Icebergcoin, etc.
TRUSTplus beat the odds with mining. They are still alive but went to 33 satoshi - which is near death. Multipool or Dev Mining strategy should be solid before a launch to cover the 0.1BTC a day fee.
