The virtual world of cryptocurrency has come from being a mysterious fascination to being an international finance universe. Two giants in the middle of this universe are Bitcoin and Ethereum. They are not only the most popular names in the crypto market but also the pillars that dictate the tone of how institutions and investors perceive digital assets. For anyone who wants to create a heavily diversified crypto portfolio, it is important to know the respective functions of Bitcoin and Ethereum. Bitcoin has been proclaimed digital gold, but Ethereum is the foundation upon which decentralized apps and smart contracts are built. Together, they make complete sense and work in such a way that risks are eliminated, possibilities are enhanced, and long-term stability is obtained in an otherwise unstable market.
