Square Cash App finally integrates Bitcoin (available on Coinbase) support. Following a trial period involving a handful of users, the payment company launched Bitcoin (available on Coinbase) integration yesterday and saw a rise in stocks as a result.

To accompany the launch, Square has also released a completely adorable Bitcoin (available on Coinbase) tutorial in the style of a children’s book, titled ‘My First Bitcoin (available on Coinbase) and the Legend of Satoshi Nakamoto‘. Through its colorful, pop-up artsy pages, the slideshow takes readers through the fundamental basics of Bitcoin (available on Coinbase) and cryptocurrency in terms an (albeit financially-minded) five-year-old could understand.

Square CEO Jack Dorsey said in a tweet: “Instant buying (and selling, if you don’t want to hodl) of Bitcoin (available on Coinbase) is now available to most Cash App customers. We support Bitcoin (available on Coinbase) because we see it as a long-term path towards greater financial access for all.”
