In this altcoin sector, I prefer to call them air coins, because sometimes they are invisible and intangible, and sometimes they disappear without you being able to track them.

I sorted them into categories: mainstream altcoins, non-mainstream altcoins, and junk coins.

What are altcoins? The following link is very detailed, you can refer to it for comparison.

Mainstream altcoins have different functions, different founding teams, and have a strong trust endorsement, a strong technical team, giving us enough confidence, I can accept it, for example, Ethereum, Monero, Litecoin, etc. . Non-mainstream digital currencies also have a relatively strong trust endorsement, especially the founders who dare to innovate continuously on the basis of Bitcoin, especially in the field of DEFI and NFT, which are also acceptable by many people, such as UNI, SUSHI , FTM, CRV, etc. The rubbish coin is pure violent marketing. There is no well-known team, no economic model, and pure plagiarism. Some will not give you tokens, and some will just run away. The entire publicity process is simple and rude, with one purpose: please Add bitcoin to my wallet address.


Has everyone been deceived by altcoins again? Please report them and tell more people not to invest

You don't understand what you are talking about. There are many good projects, like NEAR and $MAGIC that don't have the publicity or marketcap of Cardano for example, but that doesn't mean it will always be that way or that other projects are technologically inferior because of the price. It's really third world thinking. Just because you paid 50k USD for a VW car, doesn't mean it's better than some less popular 25k USD cars if you objectively compare them. Cardano has effectively branded itself despite lacking any WEB3 functionality and having slow transactions. You should be investing in promising under the radar projects before they increase in value.
