I browsed the Consensys account on Github and saw gnosis.js repository. Is Consensys behind Gnosis? I don't think it is stressed much but I admit I do not follow Gnosis too closely. While raising concerns about centralization, it nevertheless increases trustworthiness of the project for me.
this one is so overvalued. how can someone really value it more than dash?
In my opinion most of the cryptocurrency market is overvalued, it is something like contemporary gold rush or Dutch tulip exchange. But it is certainly not valued more than Dash (678M vs 118M according to coinmarketcap.com). Don't let decimal places fool you, they are arbitrary.
