Cryptocurrencies are down slightly along with stocks this morning. Bitcoin (BTC-USD) -2.4% is now trading below its 200-day moving average of about $47.1K, a technical support level it hasn't breached since the end of September. The relative strength index is still above oversold territory, north of 30, having fallen below that on Dec. 9 and 10. Rigthview Trading technical analyst Rob Moreno tweets that now there may be some liquidation of speculative positions to cover margin calls on core positions. (See his chart at bottom.) Bitcoin (BTC-USD) is down more than 30% from its recent high hit in early November. Ethereum (ETH-USD) -3.1% and Dogecoin (DOGE-USD) -4.1% are also lower this morning.
