Deutsche Bank examined whether bitcoin is improving in a recent note they sent to clients last week; a few factors have played into fees staying low, less demand with people looking to transfer their bitcoin and the SegWit upgrade to the bitcoin network; while only 14 percent of transactions occur through the SegWit update the tech is helping to improve the network; transaction volumes moving lower are the bigger reason for the drop in fees according to Mosaic.io co-founder Garrick Hileman.
