If you put your hard-earned money on a savings account, you can rub your hands when you reach 0.5% interest. After a year that’s a whopping 50 cents if you have 100 euros.

Unfortunately, most of the time a new blockchain project doesn’t provide a electrum wallet to store your coins. That means you’re left to the core wallets, which means lot of gigabytes of blockchain. It’s a waste to use your computer for that, because there’s a mini computer that can do the same: The Raspberry Zero!
