It should be an interesting next 18 months. A lot of supply could come to market between now and the halving. Mt gox payouts plus US selling 45k more coins in various tranches over the year. The fact they are selling spot rather than OTC is curious. Makes me think they want to suppress the price as part of their Chokepoint 2.0. Also, we could see extreme conditions in the economy and potentially a credit event. If Bitcoin holds up well through all this the halving narrative will likely pick up steam in late Q4 and start getting priced in.

I have no idea on number of days but if I had to guess 655 days.
