10 Tech Things You Need To Know This Morning

Good morning! There's lots of big news in tech today so let's get to it:

1. MTGox, which used to be the world's largest Bitcoin exchange, has gone offline. The Bitcoin Foundation says the exchange appears to be insolvent. Bitcoin enthusiast Ryan Selkis found a document that suggests 6% of all Bitcoins are out of circulation and that the coins have been stolen over the past several years.
2. Weibo, the Twitter of China, wants to raise $500 million in a U.S. IPO next quarter. It has about 61 million users.
3. Samsung revealed a new phone yesterday, the Galaxy S5. It's slightly larger than the Galaxy S4 with a 5.1-inch screen. It's water resistant and it has a fingerprint scanner that lets you make payments and check your heart rate by merely pressing the screen.
4. Samsung also launched the Gear Fit, which will compete with wearable tech like FitBit Force, Jawbone UP and Nike Fuelband. The Samsung Gear Fit is a fitness-minded smart watch. It has a pedometer, sleep tracker, and heart rate monitor. The wrist band can also help you locate your phone, get email and SMS notifications, and it has a built-in alarm clock.
