I agree with your opinion, there are too many crypto projects on the market and the majority of them have the same problem - no real use case. They might have cool blockchains, but if they are not being used by real people, such projects are useless.
This one of the main problem of crypto world there is alot of them and no one can stop them from spreading a lot of new altcoin are being created and no use at all. They are just full of promises and that's it is much better to avoid an ICOs since for sure they will just scam the investor.
And we all know that some of the altcoins are being deleted by exchange because they have no volume and just a pump and dump scheme.
It's the reason we should not invest without thinking and analyzing it's specific purpose and the possible things that may happen because you can't easily trust and believe their promises. Unless you have done your own research regarding that specific project and you have determine that it's a worth it and profitable project because we can't change the fact that there are some projects these days that was made to deceive and take advantage of people who don't have enough understanding on finding the best project for them. Also, scammers will always look for opportunity to get the benefits they wanted from us and that is the reason why we have to be cautious before risking our own money to avoid feeling remorse regarding our own decisions. We are not underestimating the capabilities and potentialities of these projects but because of it's ruined reputation about scams then we should explore more details and information about it before investing to assure ourselves that our funds are safe and secured from scammers. Regarding bnb, if it's beneficial to some of you then probably it's worth it. Well we can't just judge it's capabilities without even researching it, as far as I know it's useful when it comes to trading fees.
