The worst thing about this bittrex stuff is that whether or not they are intentionally scamming, because they are so fast to delist coins, it really makes for pump and dump.  You are forced to sell coins that you might want to keep, and if you are not checking the site all the time, then oyu will just lose the coins.  I have started to use other exchanges in stead because of this.  I had a small stash of epy for example.  The price dropped to nothing, but so what, I can just hold.  But it gets the delisted message, so I transfer to another exchange.  But the transfer never goes through, and both exchanges say it is not their fault.  Meanwhile epy has a rally and my coins are lost in limbo somewhere.  So I miss out on an opportunity to make some money.  I am not crying because I only had some dust in there basically, but it is still annoying.  I wish they would not delist so fast on there.
