The scaling problem on Ethereum, along with the cost of gas have been critical issues for many years. At the time of writing this article, a swap on a Dex or a borrowing operation costs around $30+, with the average gas price over the last week being 50 Gwei. During periods of network congestion, the fees can increase significantly. Not surprising that this poses a major barrier to Ethereum's adoption: a newcomer has to have substantial funds to even out the network.
Where some see a problem, others see an opportunity. Ethereum shortcomings have led to the emergence of Ethereum forks, each with its own specific features. All of them, however, primarily address the transaction cost. Ethereum developers are continuously working on this problem and numerous approaches to solving it have already been developed.
