From past few weeks whenever I open any browser or social media all I could see is some random blogs and news about Altcoins which will have massive pump and which coins I have to invest.
Well as bloggers or vloggers thats precisely what they will do. But we have our option to check first what they are shilling. Its always our prerogative to follow or not those calls. We cant say they are wrong but surely they got some narrative for that speculations cause if not then they are just trying to pump their bags and exit as soon many people put up liquidity. Not all social blogfers are leeches some are literally good on providing information but of course we cant deny presence of garbage influencers too.
The thing is that we need to do our own verification first before believing any altcoin hype on social media, due diligence is very important before jumping to put money in any new projects. Some influencial people are paid by these fraudsters to promote their scam projects, and they greedily accept because they're well paid for the promotion, not knowing the true intentions of who hired them. This is why I'm never moved when I see celebrities advertising brands, because they're just business people that are paid to do a job, ignorant people will think that if this celebrity can advertise a product that means that it's genuine. When i see a new crypto coin being advertised, I take it on advisory level, because with my knowledge i know that most of them will end up shitcoins.
The example of celebrities promoting brands was so on point, a lot of people get crazy about a certain brand or a product just because their favorite celebrity has promoted it and they think the celebrity uses it personally which isn't true. Most people, who are blind fans of some celebrities or influencers, don't know that the brands and products or anything that they promote isn't always what they use themselves but they are just paid to do that.
The same thing is for altcoins and cryptocurrencies, there are a lot of them created every week or every day, most of them don't even make it to the public, and some do make it through extensive advertisement, etc. However, as you said, they are not all good and one shouldn't believe in them just because they were mentioned or promoted by someone over the internet or TV.
