I did learnt my lesson in a hard way after being advised not to subscribe to the so-called crypto signal on a Telegram channel group, I incurred some losses in my crypto trading thus left the channel immediately, I believe those signals givers earns their money from subscribers, the more subscribers the more money they earned, any individual who is interested in crypto trading should take the bull by the horn and undergo a thorough learning, thus  acquire the skills, though this requires a lot of time sacrifice, however in the long run it worth it, that is journey I am presently embarking on to avoid signals from telegram groups.
