Let's get started.

1. Facebook could face a fine in the billions for its leak of 533 million people's data. The social-media company is under investigation in the EU for its massive data leak, and is being threatened with a fine of up to 4% of its $86 billion global revenue. ICYMI: Here's how to check if your information was breached.

2. Oracle billionaire Larry Ellison is tearing down the $80 million Palm Beach mansion he literally just bought. He told employees he has no plans to leave Hawaii, despite buying the 15,000-square-foot ocean-front house. Here's what else he told employees.

3. Coinbase CEO Brian Armstrong has a stake worth $13 billion after the company's IPO. Coinbase's shares closed up 31.3% after making their anticipated public market debut on Wednesday. These are the other investors and execs who just got rich.

4. Instagram is testing letting users decide whether to keep "likes." The app has toyed with the idea of removing likes from posts, and accidentally removed them in March, resulting in mixed reviews. Now, users can decide if they want to see or hide likes.

5. NASA's $800 million Mars lander is fighting for its life. InSight is in emergency hibernation against Mars' unpredictable weather — and if it can't save its batteries, it could die. More on that here.

6. Tesla is hiking the prices of its solar roof tiles for existing customers by as much as 70%. People waiting on installations of Tesla's Solar Roof were told the price was rising, even though many of them had signed contracts over a year ago. Get the full rundown.

7. Toshiba's CEO stepped down while board members planned to oust him. Amid a controversy over a $20 billion buyout bid, the company's board members planned to replace Nobuaki Kurumatani. Why trust in Kurumatani eroded.

9. Leaked documents show Amazon's new wireless headsets target low-income shoppers with less tech know-how.

10. After 13 months of chaos, HR officers are leaving startups — and companies can't replace them.
