UNI started with $4 that's what the price was when they airdropped to early users of Uniswap. The price right now is more than $30 it really must be a good investment and this is now in V3. It gives the privacy of ETH users while in the biggest market. Any ERC20 coins can be listed in UNI that is why it becomes big. Once the transaction fee will be fixed by ETH update, the exchange will a lot bigger.
Also, if the OP wants more information on this platform, he needs to check the social media of UNI, and see if the team is actively giving updates to its community. For those who want to seriously invest in a particular project, not only UNI, you should always check their activity. And one way is by following them in their respective social media channels. Because if you will rely on this forum, on their particular thread here, I believe, you will not get enough information. And since UNI will have their newer version, expect that there will be price increase. So for now, it seems, investing on this may be worth your risk.
