When you see a new coin think promoted the next thing you are supposed to do is to do a very good investigation on the coin for me I usually check if the coin is a decentralized coin if it is a decentralized coin I will then have little Trust on the coin, however if it is a centralized coin I will have very low trust in it after that I will check if the coin bring something new for example faster transactions, cheaper fees, privacy, interoperability, AI, DeFi, etc, i will also check How many coins exist Total supply & circulating supply I will then check if is a fair distribution or do the developers hold too much, I will na check lastly if they have strong and active communities on Telegram, Discord, X.
These are the things that will help you know the true potential of a coin before investing in it don't just see a coin and feel that it is okay to invest in it especially if it is been advertised online even though it is advertise by someone who you believe is a guru in cryptocurrency please still check if the coin has good potential.
This is a well thought idea of someone who doesn't want to fall to these scam hype coins that always pops up in the news or get promoted by social media influencers. I don't think that anyone who passes through this series of investigations that you've just outlined will end up investing in a baseless coin. All the processes you just listed is only done by few people who understand how these coins are being generated. Many other people practically follows trends and hypes then when the coin dumps and vanishes they start looking for who to blame but when they didn't do thorough research on their own to find out the authenticity of that coin.
