Anyone heard of filecoin before?

Filecoin is one of the earlier iterations of data storage. Don't see much hype in this alt coin. Especially with its competitors already out with real world storage solutions.
If you are looking for a good storage alternative, I recommend OPQ. currently trading at 0.02 cents, 16 OPQ gives you a TB of storage a year.
If it's for investment, staking coins are on a comeback, see DASH or MCO for consistent returns, otherwise just buy btc before the halving.
