It is on the top 50, but it does not means that this is a huge project, in fact, they were one of the best during the last few months, and everybody was saying that this was going to be "biggest project of the year" but they all were wrong with that predition.
It is always going down, last week it went down by more than 15%, and it just made more than -5% in just 24 hours.
I had some Gnosis on the past, and i used to earn a lot of money by trading this on Poloniex, but i stopped because the dev's started to spread bad news about this one.
When the subject is poloniex as the market maker for gnosis, I don't use certain word. They can make a classic poloniex type pump and dump on gnosis. As you know, its coin sale was poloniex leading sale couple of months ago.
