I think there's a nice opportunity to jump in on BTC for a longer term ride. If the goal isn't to time the market for quick exits and gains, grabbing BTC anywhere along this decline could provide nice long-term profits. BTC also suffers from a January dip, driven by equity investors shuffling cash around in Dec/Jan. I think the dip is exacerbated this year by greater scrutiny from regulators but I wouldn't be surprised to see a movement back up in the coming months.
