I just wanted to say "Thank you" to everyone for your responses. Absolutely agree with all of you, and I am planning to get more experienced in TA rather than relying on signals from Telegram groups. I already have money invested on a DCA basis, so just wanted to dabble a bit in shorter-term trading. I am quite risk averse, so will only invest a small amount of money to be able to learn from my mistakes (and trade on a paper basis first).
Still, many of us here have had firsthand experience with Telegram signals, which is why they advise you against them, even though some of them may be correct or very profitable signals.
Let me say that you are in the right place to learn everything you want to learn. Always do your own research and ask questions in this forum for clarification if necessary. Cryptocurrency investment involves a high risk, and in order to protect yourself from such risk, you must have adequate knowledge before beginning your investment.
