BTC definitely still has a huge impact on everything in the market. I don't think it's particularly right to write it off because it's used on the darknet though. I've bought things on the darknet and paid in GBP and USD but that doesn't make them dodgy currencies. If anything, I would say that the fact Bitcoin has managed to move away from this to now being accepted for payment of regular items is a huge benefit for not just itself, but the whole of crypto :)
