Coinbase bases this prediction on its stochastic method, which it says is both realistic and consistent with its front-end rates model. At its current market valuation, stablecoins reaching $1.2 trillion would mean absorbing about $925 billion in U.S. Treasury Bills (T-Bills), or $5.3 billion per week over a duration of 175 weeks, or approximately 40 months.
