One advantage of stablecoins is price stability. Merchants don't have to worry about price volatility when transacting in stablecoins. In the past and present, there have been a handful of projects proposing issuing altcoins (non-stablecoins) that will lead the future of crypto payment. What's the fate of such projects, will there ever be considered viable?
You have a point. Im thinking the same too, cause crypto payment is much easier if the price would not go down or up in that way, they can establish a stable grounds for any services and goods. What if bitcoin or eth have their own stablecoin like what Binance did about binance usd or busd ticker? It will help them to be more efficient on peer to peer and usable as payment gateway for some future fields that will adopt cryptocurrency.
