  Both secp256k1 and secp256r1 are widely used in the cryptocurrency industry, but secp256k1 is more commonly used. This is mainly because secp256k1 was specifically designed for use in Bitcoin, the first and most popular cryptocurrency. As a result, many other cryptocurrencies that are based on Bitcoin also adopted secp256k1 as their elliptic curve algorithm. While secp256r1 is also secure and widely used in other industries, its popularity in the cryptocurrency industry is relatively lower compared to secp256k1.
