I found thins image around social media and I am a little bit confused about this kind of advertisement, first thing, how they are able to say the future price of this coin? I guess they are just exaggerating the information that they can give to the people for the sake of sales of course.

I think they use nonsense to attract investors to buy their coins, I'm not sure if they will succeed in the future, it's better to invest in popular altcoin at least listed in the top 20 coinmarketcap.
