As for my belief in Uniswap, I will say that at the moment I have only tried the possibility of exchanging tokens once. I can’t say that I liked it, as I was faced with the fact that I had to wait for the confirmation of transactions for some time, while I paid the commission twice. It is clear that this is a feature of Uniswap's work and the load on the ETH network complicates the process, but nevertheless, the whole process is faster on centralized exchanges. Perhaps with the release of ETH 2.0, something will change for the better, but for now I don't really like using Uniswap, unless it is absolutely necessary.
