Why Bitcoin, Ethereum, and Dogecoin Popped -- Then Dropped

It's finally Friday, and while this morning it looked like cryptocurrencies would end the week on a high note, things got ugly in a hurry. Buoyed by good news out of investment bank JPMorgan Chase, the price of Bitcoin (CRYPTO: BTC) bounced nearly 2% out of the gate, Ethereum (CRYPTO: ETH) ran past 3%, and Dogecoin (CRYPTO: DOGE) briefly passed a 4% gain. Ethereum (CRYPTO: ETH) -- Elon Musk's new favorite cryptocurrency -- gave up all its gains and now shows a 0.1% loss.
