As retail space becomes less profitable due to capacity restrictions, many retailers are forced to relocate or move their product selection online. Square's acquisition of Weebly (website builder with e-commerce functionality) will help them challenge Shopify's market share for online stores & purchases. Additionally, Square is establishing themselves in the payment processing space with Cash App, a mobile application that's quickly climbing up the ranks and slowly diluting Venmo and PayPal of their market share. Cash App also allows users to buy and sell Bitcoin, and will potentially offer other cryptocurrencies in the future. Due to the company's existing trust factor, another step further into the cryptocurrency exchange space may be extremely rewarding.
