I am sure with this new eth 2.0 system we are going to see much better fee structure and thanks to that there will be a lot better dex platforms that would be used without a problem. I don't know how they are going to deal with it but 2.0 is not something that only focuses on going from proof of work to proof of stake, that is just one part of it, the other parts probably consists of some fee restructure as well because if it doesn't that is going to have a bit of a problem.
However at the end of the day it is us that decide on the fees and the quicker we want to move it the more fee we pay, if all of people who use gas suddenly decide to spend a lot less on fee's we can drop it all together. But everyone wants to pay one gwei higher than others and that keeps making it higher and higher.
That's certainly true, mate. The next iteration of the Ethereum blockchain, will certainly improve the fee structure at every level. While the reduction in fees will be noticeable in the short term, additional work is needed in order to keep it that way. Eventually, the Ethereum blockchain will become clogged up as more people join the "De-Fi" craze. Dapp developers are going to need to consider migrating to second-layer solutions in order to maintain fees at their lowest level. It's a collaborative effort between the Ethereum project developers, dApp developers, and individuals as a whole. Otherwise, fees will continue to soar, making Ethereum no different than Bitcoin itself.
With high fees, "De-Fi" will no longer be a viable option for those looking into "decentralized banking". The "De-Fi" industry will only be related to the wealthy, as they'll be the ones capable of paying exorbitant fees on the Blockchain. Luckily, there are several competing blockchain networks with greater transaction capacity than Ethereum. Some say that Binance Smart Chain (powered by BNB) and EOS are Ethereum's top contenders in crypto land. Binance's own blockchain network enjoys of unparalleled performance, while being compatible with ETH-based smart contracts. There are many promising "De-Fi" apps on the BNB blockchain right now. They're certainly much faster and cheaper to use than their ETH counterparts. Ultimately, people will decide whenever they'd want to pay high fees on a blockchain network or not. As long as people choose to pay high fees on the ETH blockchain, "De-Fi" won't be going anywhere. Just my opinion
