If the purpose of buying signals is only to find convenience in trading activities. So it's not recommended at all. Because there are many fraudsters out there who are not very skilled at trading but claim to be the most skilled at trading. Learning it autodidactically from YouTube is indeed a solution. But I prefer to suggest learning from free groups that provide free crypto education and crypto analysis, which we also find a lot on Telegram. Because on YouTube, usually the information you get is always the latest because the process of uploading videos and editing videos takes time for content creators. Meanwhile, on Telegram, information can usually be obtained more quickly because usually the channel owner on Telegram is also a trader. So they are much faster in updating information. And delivering analysis is also more comfortable. Because sometimes on Telegram there are also trading crypto channels where Live Video Calls/Voice Calls are held while trading together. I ever took part and it was quite useful. And the most important thing is that it's all free without having to pay anything.
