Having been slightly burned by the Bitcoin phenomenon, I've never got into Ethereum, a newer cryptocurrency, but there are plenty of tech-savvy people who are invested in it. And here's a UWP application to help you manage your 'wallet'. On phone, tablet, laptop, HoloLens or even your Raspberry Pi, all running Windows 10.

From the Store description:

EtherWallet for Windows 10 (version 2) is Feature Rich, One Stop Ethereum Wallet on Windows 10 devices. These current release support the following features:

• Create Ethereum Address
• Add existing Ethereum Address (restore backup from MyEtherWallet)
• View details of Ethereum Address
• Send Ether to another Ethereum Wallet
• Monitor Ethereum Pool mining progress
• Save/Backup individual Ethereum Wallet/Address
• Save/Backup entire Ethereum Wallets/Addresses
• Import MyEtherWallet directly

• Support Self-Service Access Code Reset

I don't have any Ethereum, so I'll rely on Store promo screenshots here:

The core Wallet screen and something err.... to do with mining. Does this mean you can manage a mining pool? Hmm.... Anyone know?
