Most of the projects are scam there , some of them are an unknown team and you don't know if they have locked the liquidity or not, and even after that they could still rugg you by dumping on you seed tokens or private sale tokens, I got rugged there by a project that was partnered with ferrum!
called TMPL , and after that I'm not touching that again!
Project nowadays can be legit and most of the time not. How did you ending up investing to those Uniswaps? are they the same as others that have promised good results to their investors?
I'm sorry with your loss.
its something like decentralised exchange which you need to connect your wallet and you can able to buy any tokens listed there by just searching for its ticker the good thing is there are value already when you look at the coins and the liquidity of that exchange. The bad thing is it can also be abuse in the future .
