Simple big holder of coins (Whale, Investor) is sell off. It has nothing to do with the coins fundamentals. They will either buy back at the cheaper rate or move on to the next big thing. Once they are done the price will stablize. Does seem a bit funny that we release all kinds of things like 1st staking Android wallet etc and get not one piece of news yet an article appears 2 minutes after the 25 btc sell and mentions it in it.
