$55 billion is a massive amount of profit to make in a single year. This has indeed got to be an inspiration to the banks. And I feel more are going to jump right into cryptocurrencies which I feel is the easiest currency to exchange. This especially should be adopted by African banks which have amassed huge amounts of debt, inflation keeping getting high.. Making such abundant profits would deliver the African governments from the financial turmoil they are in as they would be able to cash in on the growth of resources instead of borrowing to have them grow.
