Crypto Rider lets you ride the thrilling roller coaster of cryptocurrency prices

Martim Lobao

For most people, investing in cryptocurrencies is already enough of an emotional roller coaster as it is.

Latest Circle Update Gives The Bitcoin Wallet App Support For Android Wear And NFC

Bertel King, Jr.

Circle is an app you can use to manage bitcoin, assuming, you know, that you're into Magic Internet Money. The latest update adds Android Wear support, which gives you the option of generating a QR code to use as an address for receiving byte-sized moolah or simply keeping an eye on bitcoin's going rate at the moment.

This update also adds NFC support, so you can use the app to transfer bitcoin by tapping your phone against something it plays along with, just in case paying using Google Wallet doesn't provide enough nerd cred.

All half-joking aside, there's reason to be interested in decentralized digital currency. With a sleek Android app and Wear support, this continues to look about as pretty a way to manage your bitcoin as any.

Ryan Whitwam

Advanced 3D graphics! Dual-stick controls! A deep, engaging story! Bitcoin Billionaire from Noodlecake Studios has none of those. Yet, it's still somehow addictive and... I don't know if I'd say fun, but something resembling a type of fun.

Bitcoin Wallet 'Circle' Comes To Android To Make Magical Internet Money Less Confusing

Ryan Whitwam

Bicoin is a neat idea, but it's not very easy to use. In a world where most people have trouble figuring out how a ZIP archive works, asking them to manage their own encrypted Bitcoin wallet file is probably not going to happen. Having a third-party do it for you is risky too, but Circle aims to make Bitcoin safe and easy to use. The new Android app looks pretty great too.

Android Bug Creates Weakness In Virtually All Bitcoin Wallet Apps, Money Vulnerable To Theft

Ryan Whitwam

Bitcoin is still emerging as an online currency, and that means issues are sure to pop up in the way it's implemented. This time there's an Android-specific problem. It turns out there's a weakness in the way Android generates random secure numbers (the Java SecureRandom class), which most Bitcoin apps use to create wallet IDs. That means an attacker could possibly figure out your wallet key and swipe your digital cash.

Anyone that generated a Bitcoin wallet key on an Android device is potentially affected (even if it is no longer used on Android). Keys generated elsewhere and simply used on Android are not vulnerable to the potential attack.
