I would say filecoin is more similar to sia or storj than shift. Becaureful investing icos, maybe be wiser to wait till the coin is on an exchange. How many icos release their coin and it goes below the ico price? Also keep in mind sia and storj already have working products, they are way ahead already. Why not invest in those instead?
I'm with Fantum on this one...Invest in technology that actually exists and a proven track record.
I don't support Storj because it is centralized, but some people like that.
I personally use the Sia technology, which means a lot.
