There's also the option of exchanging a chunk BTC for LTC from time to time to make small purchases more feasible.
Not in America, when the IRS will charge you capital gains for just doing that exchange.
Plus the fact that still to this day, almost no merchants in the U.S. where most people shop (or buy coffee) take ANY crypto directly as payment.
Over the years, I've grown extremely weary of conversations of the "theory of using cryptos for daily purchases" vs. the reality. The practicality is non-existent.
