the question was to name legitimate businesses doing ICOs. filecoin is certainly legitimate. You are talking about how their tech might fail and how their business might not work. that's great, and you could very well be correct, but that's not what we are discussing here

I am rather certain that guys consumed less-legal substances while drafting their whitepapers. That is my top reason not to consider their business "legitimate".

You didn't make a point, sorry.

ok, to those who didn't get my point. Everyone is certainly entitled to make up their own definition of "legitimate". However, as long as we are all speaking English, we can agree on what legitimate means. And it means the following:

le·git·i·mate adjective adjective: legitimate ləˈjidəmət/ 1. conforming to the law or to rules. "his claims to legitimate authority"

so, it's great to have a learned opinion on filecoin's tech, but its irrelevant to the discussion of whether filecoin is a legitimate business
