Just got some information/news that people are selling $100,000 in Bitcoins to buy gold. The money they are getting by selling Bitcoins is used to buy Gold
Gold is the safest investment. See the link
The btc price is down due to many reasons and the impact of many factors. I do not think people are selling btc to buy gold, besides, it is impossible for people to sell out at once, causing the price to drop so fast. When btc is in good developement, they sell btc for $ 14k and buy gold, which seems unreasonable.
