The whole matter looks strange to me, because I even tried to imagine the length of time it took Bitcoin to be valuable, trusted and so on, but these ones all of a sudden comes out, starts pumping and people couldn't get enough of them because they keep going for more of them. Also, as for Uniswap, I would say the team behind the exchange are just trying to get their own share of everything thus not bothering about auditing the projects they list. Same is with the people chasing after all these projects, they don't care of what the project offers so far they can get their own share. So one can see, on one hand, Uniswap cares only about the gain same with the investors but on a more serious note, only the team of that project makes much gains while deciding the fate of all investors.
Lastly, I wouldn't say it's like bitconnect but however, people need to take a break and ask themselves questions about all these projects they are investing in.
