You've probably heard of Bitcoin once or twice by this point, even if you're not entirely clear on how it works. Until now you've needed to be familiar with the entire process of producing, storing, and spending Bitcoins for the currency to make any difference in your life, but a startup called 21 wants to change that. 21 is pushing Bitcoin mining as a built-in device function. This won't make you rich, but it might change how content and services are managed.
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.
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.
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.
Here at AP, we usually team up with partners to give away Android devices, accessories, or other related items. Every once in a while, though, someone hits us up with something new and different. Something fun. That's what today's giveaway with Handy Apps is. Before we get into the details, however, let's take a closer look at some of our kickass sponsor's apps.
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.
