There are only two or three memecoins, which are established well and going on as trustworthy altcoins. And rest of memecoins are shitcoin and thats known to everyone. But high expectations makes people blind and they invest with memecoin as well as shitcoins without think of the consequence. And many have been go below with their Capital, for this reason. But i dont agree with all of your points. Point 2, Every project make promises, so based on promise you can't find out the shitcoin. Point 4 is fair but in this forum most of people are helpful and they suggest only top potential coins.
Not a single memecoin is trustworthy, because these are useless altcoins from which there is no practical use, and the cost of these coins is extremely inflated due to hype, news and rumors. The fact is that faith in these memecoins is based only on the basis of price speculation: they want to buy cheaper in order to sell more expensive as soon as the fools start buying it en masse. These are the consequences that people blinded by greed think about. Of course, there is not enough money for everyone, and therefore, whoever
enters the game later gets a loss. Memecoins are more like pyramids in nature.
About points.
4. People are ready to help with advice, but the nuance is that there are many different points of view and try to understand which of the tips will turn out to be true. In general, people can be trivially wrong at times, therefore, relying 100% on the voiced promising coins is not at all an option.
