Coinbase has capitalized on this explosive growth, putting up jaw-dropping financial figures consistently over the past year. In 2021, Coinbase's revenue skyrocketed 545% compared to 2020 to $7.36 billion. What's even more impressive is that the company has been able to grow its profitability even faster. For the full year, its net income soared 1,025% year over year to $3.6 billion, while its free cash flow -- which primarily consisted of growth in custodial funds -- reached $10.7 billion over the same period.
