This cheat client is private, and not everyone can use it, because it costs as much as $ 20. However, one person managed to hack this cheat and get access to all the functions without paying.
Future Hacked client Minecraft 1.16.5/1.16
This cheat client is the most popular of all private cheats. They buy it, albeit for $ 20, and for good reason. Everything from the fact that it has powerful features that are updated every week and modified. With this cheat client, you will definitely go unnoticed on most servers, not just 2b2t.
However, it is worth noting that you need to run the cheat client without an Internet connection (then you can turn it on). Also, it will not work with the licensed version of minecraft and will not be updated in the future.
