On NVO website we can see number of invested cryptocurrencies: BTC, LTC, ETH, ETC, DOGE, DASH.
Don't forget Ripple and Maid.
Is there a way to see total number of all invested money, preferably in the form of USD, without having to count every single one of them?
That is not available at this time. The developers could add it considering that there is decent demand for said feature.
I simply would like to have clear, fast overview.
It's only a little bit of math, but I do agree that it is inconvenient to do it each time.
