I can say it is a scam signal channel, there is no such thing as free in this market. At first, the creators of these signal groups will be free, and then they will make you pay to keep getting false signals, and you will be the loser in the end. You say you have been in the market since 2017, and you are still looking for a bunch of free signals sounds like you are also a scammer.
Most of them are likely scam signals channel. They will give you what you want and what you think is right while you give them money. They market the "free" signals at the beginning but they'll ask you to pay for some "premium/vip" separated signals. LOL!
It's very obvious that what they start with, is not what they are going to at the end, because once you join the group you have been under their control and under their influence, many some people who knows the methods of people who claims to give or issues a free signal will tell more better. Because they most ask for fees, so it's better to learn how to study the chart of cryptocurrency, because this cryptocurrency understanding of the chart, it's better than following some people you even know more better.
I've seen others that did this and they're making it look like they're asking legitimately but they're not. Look, the guy won't come back anymore and that's already enough for him.
