Why do we need stablecoins to pay for groceries when we already have bitcoin and probably other cryptocurrency that can be used to pay for the groceries. Don't forget stablecoin weren't introduced into the industry to replace bitcoin and other currency but was introduced due to the need to minimize losses when the market is experiencing a downward movement. Beside things like this might discredit the importance of cryptocurrency and we should be more willing to utilize our coins and not just use them as investment vehicles (store of value).

They should be spent like how our everyday fiat currency is been spent although not misused like the OP is suggesting e.g ethereum been used as a currency to pay for groceries when the likes of bitcoin/Litecoin is present etc.
