The US dollar is weakening just like last January and that adds support to Bitcoin and ETH. If you look at the chart of the US dollar it hit 97.5 five times and failed to go higher now it has turned down. In theory as the dollar drops if your holding bitcoin or ETH you might be better protected so things are lining up pretty well for an early January rally in crypto in my opinion and ETH with the upgrade showing real progress should lead the crypto pack in my opinion. I wouldn't be surprised to see some Institutional buying through Coinbase in January because they probably didn't want it on their books for 2018 but 2019 is a different story they may fear they will get left behind in my opinion. Facebook in the early days didn't stay down for long because the network effect kept growing same here applies.
