I literally just did a huge rip on crypto currencies the other day, mostly regarding bitcoin. However, there's one aspect to Filecoin that I do see as... potential is a strong word, but maybe appropriate still. It's not entirely fair to lump it in with other cryptocoins. There is some value behind it, in means of distributed storage. While I would argue it's more efficient, easier and all around better to use standard alternatives since Filecoin adds a layer of complexity to marginal benefit... I can never argue it's completely useless. There is some economic value backing it since it provides a service outside of just being a cryptocurrency.
If I woke up from a 15 year coma and was quickly told about Bitcoin and Filecoin, one had a value of $200 each, the other $50k. Then asked which one was the $50k one? I'd first say, "Filecoin obviously" and second, please just kill me I don't want to live in this bizzaro reality.
