Today, most stablecoins track the value of fiat currencies but we might see the adoption of coins pegged to valuable assets like gold. These might, in reality, prove to be the best for when “paying with crypto” due to possibly being inflation-resistance. But for day-to-day transactions – whether using BTC, ETH, SOL, etc. – transaction and conversion costs will be important. The cost of paying for goods and services would need to be less than the average 3% transaction fees imposed by large credit, debit and app payment processors to prove valuable to merchants.
