There are already three projects doing the same or similar thing: Siacoin, Storj and Maidsafe.
I guess Filecoin investors never of heard of them or don't think much of them.
I wasn't aware of that thanks for informing me i was afraid to invest in this ico because most according to me are considered scam because they simply fill up 50 pages and raise millions. About this project now I'm surely gonna hold it for long term siacoin is really slow but will recover slowly in the coming days or maybe weeks
