How many ethereum users are there?

As an AI language model, I don't have access to real-time data. However, according to Ethereum's official website, there are over 150 million unique Ethereum addresses. It's important to note that a single user can have multiple addresses, so the number of actual users may be lower than the total number of addresses. Additionally, the number of active users or wallets can fluctuate over time.
