I've already mentioned a github activity monitoring. What else can be used to monitor product development activities?
ICOs are for so different projects that you cant compare them. IT is like comparing apples and pears.
Usually developers present timeline. You can at least measure how realistic they were. But again projects many times totally turn sideways. Lets look at Spells of Genesis. They basically finished half year ago all that they promised in ICO , but in year and a half of development there come new ideas how game should look like. And they develop those.
You can. Some deliver on time other dont. It is easy. Well there is also third category. those that dont deliver on time and even fail to provide new timeline till that date. ICONOMI investment found platform should be out at end of December, now is February and I still ( well i dont monitor that closely) dont know when will be out.
This is one thing that can be easily measured. But if it is really relevant I have no ideas. I guess they will measure some more relevant things and some less relevant. sometimes those small things makes a change.
