I think Bitcoin fees have reduced recently. Is it due to Segwit?
The fees have gone down considerably and that is because of the total number of unconfirmed transactions having dropped from an average around 150,000 down to around 50,000 right now, according to blockchain.info. That's a considerable drop considering where it used to be at, and being one-third of the quantity that it used to be at is nothing less than a major statistic for the rest of the network.
The full-retard hype is over now, and we're seeing a transition back to the "normal" existence of Bitcoin. It'll see a lot of things slow down a lot.
Yes I think this too. Fees are lowering because less people are using it. Segwit has not been adopted widely yet.
