For perhaps the most egregious example of this, look at the "Cardano" project. It does nothing, without any apparent plans to even change that. Even their hello world example doesn't run. And yet it is the #4 ranked cryptocurrency, with a market cap of $44 BILLION dollars.
All of it appears to have stemmed from their founders doing these creepy aspirational youtube live streams. If you're still investing in cryptocurrencies at this point, seriously look at that project and tell me that this space is reasonable. This is the 4th most popular project behind Bitcoin, Ethereum, and Tether (an obvious fraud).
