Indeed, it is strange how Uniswap suddenly rose to prominence, commanding such huge trading volumes. However, I think it makes it difficult for experienced traders to use when it comes to using charts, signals, and analyzing the best entry and exit points. These are features you'll normally get when using a centralized exchange.
I also agree with you, Uniswap suddenly gained the most exposure. Uniswap is a decentralized exchange platform. As it is a decentralized exchange, it cannot control transaction fees alone; Depending on all network conditions, such as IDEX, EtherDelta and other ERC20 decentralized exchanges, this huge fee could affect the credibility of Uniswap if the gas problem persists, even if there is nothing to do about Uniswap's gasp.
