I read your previous posts and the last one in which you explain the difference between buying and mining Bitcoin gives the impression that you have some basic knowledge of how everything works. In addition to all the information that can be found on the forum, it is really strange that you are looking for a source of some new information on Telegram...

I also see that you are interested in buying mining equipment, and then you better stay away from various social networks where there are a lot of fake sellers - unless you want to risk paying a few thousand $ for a brick.
