However, the success of Bitcoin and Ethereum is not merely determined by miners. Other individuals from the community are supporting the blockchain in different ways to make both blockchains a success. Their form of contribution include technical development, business development, marketing, and community-building. For example, some may create an exchange to allow people to enter or exit the cryptocurrency market. In contrast, others may develop a wallet enabling users to receive, send, and store their crypto assets. Despite the importance of their contributions, there isn't a well-designed mechanism to reward these activities as Bitcoin/Ethereum mining does.
