As everyone advised you, Telegram is not a good place to learn any information about Bitcoin or miners. You should take your information from trusted sources such as this forum or popular blogs in cryptocurrency and famous YouTube channels. The telegram contains thousands of scammers, It will be difficult for you to learn safely and they may steal Your money and bank accounts, so you should be careful and not click on any suspicious links from unknown people asking you to download a fake application or put your private key in the fake sites.
good choice both indeed this forum and some articles available like coindesk, cointelegraph etc. I never recommend joining the telegram group because many scammers will start luring new people into their traps. it must be full of caution wherever it is. What is certain is that this forum is the main recommendation because a lot of knowledge is already available in full, as long as you want to read and focus on what you will learn.
