Reports show that BTC transactions accounted for $1.3 trillion in 2018 alone, outperforming all PayPal transactions for the same period. Visa accounted for a massive $8.9 trillion in 2016, but with a trajectory of an 80.17% growth per year from 2013 to 2018, BTC will also overtake Visa in 2022, theoretically handling over $13 trillion in payments.
