Because many investors in the cryptospace are only in it for fast money. If it starts to dip, they sell to maintain their profits.
Maybe you're right they are just looking for cryptocurrency because they think they can earn big profit easily without studying what is all about and those investors like this are the one who always panic and then sell their cryptocurrencies which is wrong if we are going to analyze it intelligently.
topics and comments are the forum do not represent the majority and you certainly can't make a conclusion based on them. most of these topics are from people who don't even hold any kind of cryptocurrency. they spam the forum for payment and dump it all for fiat immediately in their exchanges where they receive the payment. specially when you go to altcoin boards they are just bounty hunting for free money.
the real investors (the majority) aren't wasting their time on those silly topics.
You're right most of those post came from the paid spammers but not all some investor's are already influenced by those non-sense panic selling thread that is also why I posted a thread like this at least to help some real investor's to be enlightened.
I've noticed this too, and I think it's because everyone thinks that they can collect a bunch of free money around here. I don't see anyone handing it out so don't know why people go through so much effort just to spam all corners of the internet. I guess if you put it out far enough there will be some sucker somewhere who will eventually open his wallet.
It's good to share legitimate information about crypto because that's what we're here for. Unfortunately, it's hard to know enough information sometimes and we just have to sit on our hands and wait.
