That is the reality for most of the signal groups. They all act that they are an expert and they also act that they know what is going to happen in the market but in fact, they are just buying random altcoins from the market and advertise it as a hidden gem for their followers to buy it and boost the price up. Do not join into any pump and dump group, just focus on yourself and own strategy and you will reach success.
People need to use their common sense, if those people that organize those groups actually knew what it is going to happen in the markets then they will not be trying to scam people on the Internet with their pump and dump groups, they will be trading their money and earning a fortune with their system, it is better to just ignore them and never give in the temptation to try their services because most likely you are going to lose any money you invest with them.
