Congrats, you have now entered the 'Crypto Veteran' stage and you are now able to see through the bullshit.
You're now at the point where you no longer think market manipulations and such are 'nutty conspiracy theories' but in fact realize that this is exactly what's going on on a daily basis. News is being manipulated, shilled, and whatnot. 90% of the altcoins are indeed shitcoins, including some of them that sound great.
With regards to the paid shilling you really need to remember this too and most of all remember that it is not just in crypto where this happens. These paid shill tactics are 1000% also going on in political campaigns and other initiatives to try and attempt to change the public opinion. Most of the loudest voices on pretty much any subject have a big chance of being 'fake'.
It's like the early days of commercials where people were unable to seperate truth and lies in commercials either.
Now that you've discovered the dark sinister truths of crypto, it's time to seperate the crap from the gems and ditch the 'shitcoins' or simply start seeing them as ways to earn more of the gem-coins.
While much of crypto is a money-grab, there are projects which are solid and have actual purpose and value. For me, these are some of the more established coins. Bitcoin being the primary one, but coins like ETH and XMR have merit too. Personally I am leaning toward Bitcoin maximalism more and more, though the majority of my portfolio is in alts.
