Nearly every single coin is down ATM because of bitcoin bull rally, except for some rare quick pnd (but with very low volume), so VRM is just following the global alt trend.
ETH is crashing, XMR and ETC are very low, LTC crashed, ZEC is crashing (also because the mining ramp-up just finished), DOGE is crashing... VRM maintaining itself would be extraordinary, but there's still no reason for it to do so.

Interesting fact is that bittrex daily volume this past few days is less than 1k BTC, which is very low for an exchange with a full dev team, and I don't know how they can survive with fees alone.
They have ~200 BTC markets and today for example, only half of them had the minimum 0.5 BTC.

It's very strange for them to want and try to delist so many coins when we're clearly in a very alt bearish market.
I mean, even VIA which recently had a major dev change is in danger of de-listing.

It's a shame they equal development quality with volume, especially for recent ones that could not prove themselves yet.
In the case of a coin that everybody wants to hoard for staking, thus having very low exchange volume, it's just stupid.

One would suppose that the exchange is currently in a difficult financial situation, and they're trying to cut a lot of operation cost by halving their alt market count in a way that put pressure on devs/communities.
But that may very well be a bad strategy, because if the only alts remaining are the high volume ones, those are probably also on poloniex, and why trade on bittrex if you can do it on poloniex with much higher volume.
