Coinbase and Gemini, two of the biggest cryptocurrency exchanges, both crashed this morning as the price of Bitcoin skyrocketed past the $11K mark. I'm sure this really ticked off a lot of people because they weren't able to login and sell as it peaked and now Bitcoin is back down to around $9K in value. I expect this to get worse as the bubble continues to expand. It's not going to end well for a lot of naive people.
