How are they doing this?
In every investment, there will always be newbie investors who are easily attracted to these new projects.
High APY, burning mechanism, dividends just by holding. These are just some of the few ways to attract these newbie investors and sad to say, there are some who are falling into it and there is nothing that we can do about it.
How and where are they getting the buyer from?
Online. Like I said, they are just inputting some flowery and attractive words that can attract investors to invest into their project.
Right now, these meme coins are just the same and to my surprise there are some who became successful to gather some buyers to support their project. Most of them though ended up as a dead coin or a scam coin.
Is there a secret to this?
There is no secret into this.
Also what is the correct way to gather community members for a new project?
Advertising into different social media platforms. I think that is the correct way to gather community members. TBH, I don't know how some meme coins are gathering tens of thousands of members in their channel especially in their Telegram. Its also possible that most of their community members are paid just to join in their channel.
