Majority of my holdings are still in BTC. I'm not worried about the price drop at all. This is just the natural ebb and flows of Bitcoin. I would guess it'll go lower, but keep in mind Bitcoin's MASSIVE network effect (which is growing every day regardless of price). That's the main reason why I'm still long term BTC.
I think this price decrease is from Ethereum selling off some of their coins as well as merchants converting BTC instantly to fiat.
