As a follow-up to yesterday’s show about cryptocurrencies, one of our listeners wants to know if Coinbase, which went public today, is really a reliable way to buy and sell bitcoin and other blockchain-backed assets. We’ll try and answer without thinking too hard about the money Molly might have lost when another exchange got hacked. Plus, your questions about vaccine appointment bots, the fallout from the mess in the Suez Canal and Kai pulls back the curtain a bit on “Marketplace.”

Here’s everything we talked about today:

• Revisit some old Marketplace reporting on Mt. Gox

• “Meet the vaccine appointment bots, and their foes” from the Associated Press

• “Egypt impounds Ever Given ship over $900 million Suez Canal compensation bill” from CNN

• “Ever Given Customers Face New Payments to Get Shipments Moving” from The Wall Street Journal

Finally: We need your voice memos! Tell us what you think of the show or ask a question for Kai Ryssdal and Molly Wood to answer! Here’s how to do it.
