Imagine walking into your favorite coffee shop in 2035. You order your usual latte, but instead of pulling out cash, you scan a QR code and pay with a fraction of a cryptocurrency. The transaction settles instantly without the help of third parties like banks. On the other side of the counter, the cafe owner receives payment directly into their digital wallet, with lower fees than today’s credit card charges. Well, such experiences are not far-fetched, as more than 15,000 businesses globally accept Bitcoin payments.
