The bubble has popped and the euphoria has tuned down. However, the stable coins market is a $1-2trillion market (https://defillama.com/stablecoins), so there is still a long way to go/grow. Other cryptos like Bitcoin and Ethereum will continue to exist. Bitcoin mainly as an asset against the stable and Ethereum as a network to process defi transactions (you can exchange stable coins for crypto without an exchange now).
