Coinstar Adds Bitcoin ATMs to Walmart Retail Stores

Following a collaboration with Coinstar, Walmart customers can now make use of 200 Bitcoin ATMs in the retail giant’s pilot program.

The process of buying Bitcoin through these machines is straightforward but relatively costly. Shoppers will insert banknotes into the ATM, which will then issue a voucher carrying a redemption code. The voucher can only be redeemed after the completion of the Know-Your-Customer process. According to the Coinstar FAQ page, “Each purchase carries a transaction fee of 4% and a cash exchange fee of 7%.”

Translation: If you really want to buy Bitcoin with cash, this method may be a good option for you. Otherwise you can buy cryptocurrencies through exchanges. Privacy downside: Many of these exchanges are required to use a Know Your Customer (KYC) process. Upload your photo, driver’s license, and fill out other personal information.

Battery Buddy Makes Charging Your MacBook More Fun

Let’s face it, the default battery indicator on MacBooks is pretty boring. If you want to liven it up a bit, consider the terminally cute (and free) app Battery Buddy by Neil Sardesai. This indicator shows your MacBook’s battery charge using cute smiley faces. Fully charged, the indicator smiles at you, but he grows less happy and more sad as your battery drains. When you plug in, your little battery buddy gets a charging icon next to him.
