The Brave web browser has carved out a niche over the past few years as an alternative to Google Chrome, Mozilla Firefox, and other mainstream web browsers. Some of that has come from its marketing as a privacy-preserving web browser, and it has also been repeatedly evangelized by cryptocurrency enthusiasts.
If someone recommends Brave to you, you should ignore them, because they are wrong. Brave Browser is a mess of a software project, and the company building it is even worse.
Do not use Brave. It’s a Chrome skin from a slimy company peddling crypto schemes, building an ad network, hijacking the URLS you type to get affiliate money, ran by a homophobe. There are so many better and less sleazy alternatives.
Use those instead.
