I think it is very smart to invest in both bitcoin and ethereum because they have a future. Bitcoin was originally invented as a digital store of value and also a payment system. the ethereum was invented as a global computer to handle smart contracts, it has so many good projects going on such as Decentralized Finance known as (Defi), Non-Fungible Tokens known as NFTs, and finally but not least, they are moving to ETH 2.0 (Proof-of-Stake) Blockchain.
