Mastercard is planning to offer support for some cryptocurrencies on its network in 2021. It is worth noting that Mastercard offers cards that allow users to transact using cryptocurrencies, although without going through its network. This has come after Elon Musk’s Tesla said that it had purchased $1.5 bn of bitcoin and would soon accept it as payment. BlackRock, Square and PayPal have also recently backed cryptocurrencies.
