Monero is a cryptocurrency which has privacy related features by default. Unlike Bitcoin and similar cryptocurrencies you can not see how much Monero an address owns. Monero is perfect for anyone who values their privacy. In the twenty first century almost everything you do leaves some type of bread crumb for people or companies to track or sell your metadata. Some people argue that do not care because they have nothing to hide . Just because governments or companies have the ability or resources to track your metadata and habits does not mean they should or make money with your data. With Bitcoin if you paid for a service with Bitcoin, the employee could see that you have $10k worth of Bitcoin in your wallet. They might try to scam you out of more money or try to $5 wrench attack on you. With Monero, the employee has no idea how much money you have.
