Back in 2017, many ICO projects pride themselves of having one of the biggest telegram community. Some of them would market it as a proof or sign that many investors believe in their project. People who have been around all know that most members there are airdrop/bounty hunters who only joined to qualify for the reward.
I also saw one
post earlier asking for telegram group members and one of the condition the buyer posted is that it "needs to look real".
Anyway, this post is just a reminder to beginners in crypto. We don't want you to fall for these tricks to lure you into investing into their projects.
I agree that we should not invest based only on the size of the community in the telegram group. The number of members in the telegram group does not reflect the project or investment interest. In my opinion, it's better when deciding on investments, based on liquidity and active trading in the market
