Dogecoin races higher again after Elon Musk tweet

Dogecoin (DOGE-USD) pushes higher after Elon Musk is positive on the cryptocurrency once again. "Working with Doge devs to improve system transaction efficiency. Potentially promising," tweets Musk. Dogecoin is up 29.98% to $0.53 on 24-hour volume of $21.5B. The market cap of Dogecoin is just over $68B, which makes it more valuable than Moderna, MetLife and General Dynamics at the moment. Meanwhile, Tesla (TSLA) is up 2.88% on the day due largely to some investor optimism on a new battery supply deal in China. Some analysts think the cryptocurrency confusion from Musk and Tesla over the last week has weighed on the stock's valuation.
