I completely understand your frustration. I recently came across an article on Pro-Reed titled "Exchange Crypto Currency in One Click" that explores exactly this concept https://pro-reed.com/2022/09/21/exchange-crypto-currency-in-one-click/ . The piece discusses how some modern platforms have streamlined the exchange process to just a single click while maintaining strong security measures. The article explains the technology behind these instant exchanges, including how they manage liquidity and protect user funds. What impressed me was their analysis of how these services can significantly reduce the time and effort required for crypto conversions while still offering competitive rates.
