Zumo, an Edinburgh-based mobile wallet and payments start-up backed by Coldplay bassist Guy Berryman, has launched an app that stores, sends and allows consumers to spend and exchange cryptocurrencies online.
Today, customers can use the app to buy, sell and exchange both Bitcoin and Etherium cryptocurrencies. Since the start of lockdown in March, the price of Bitcoin has risen sharply as retail investors rush to Bitcoin as a safe haven.
