Never rely on those trading signals because they are not guaranteed to be accurate. Some groups are even scam because the information they provide is just to create a pump and dump movement. Before they give that particular signal, they already bought some of it waiting for their followers to buy also and dump their holdings on them. Even if you find a group where an experience trader shares a trading signal, it's not good to just rely on them. People like them won't do it forever so it's still better to learn at your own because it will benefit you in the long run.
