I think the D3 debacle showed how early and underdeveloped crypto still is. Crazy to think of the power Bitmain (and other mining companies) has especially if their incentives don't fully match up with the devs. Long term I think the hope is for the price/volume of the currency to pick up exponentially to a point where the network needs all the hashing power.... But yeah got burned on some D3s but when in doubt either hodl or sell literally have only 2 options.
