hello，friends，i want to know more about bitcoin and miners, could you recommend some telegram links to me, thanks a lot.
Be careful of telegram groups. Avoid person messages, tmif anyone send your PM, they only want to scam you. Just follow some of the links provided by the reputed members above and read online yourself about mining. Avoid scam. Mining is required a lot if things like having cheap electricity, buying expensive mining hardware's like ASIC that cost thousands of dollars and also joining mining pool.
Do not go for those cloud mining and other ones, they are scam. Anyone or online site that said they can mine for you are also scammers. If you can not buy mining hardwares and join a mining pool, you can go for other options like holding.
I really have to believe that OP is not a newbie in cryptocurrency, if he is, he wouldn't have known about Bitcoin mining, but my fear is that is he surely knows about Bitcoin mining or has experience of it, he should know where and how to locate such telegram groups. I pray Op knows what he is doing.
The OP seem more like a newbie post. What can come some newbie mind is to to search online about tmhow to earn bitcoin, what would be included among it is mining. It is very easy for newbie to easily have heard or read about bitcoin mining, but mining is not easy as it is included on the articles of how to earn bitcoin.
