What is the highest amount of cash you have gained and lost on a crypto currency in a relatively short amount of time?

I have always been curious to see where other people in the community fall on this. I personally made and lost $3,000 on Ethereum back in 2021 during the bull run and then crash. The most I’ve made personally in an incredibly short amount of time was 1200 ish dollars on DOGE in one night. Surprisingly, I got out of doge before it imploded from its all-time high. I’ve heard stories of others who gained and lost thousands and thousands, and it’s always interesting to read up on others successes and failures. What I’ve gained and lost isn’t a large amount to a lot of users on here, I’m sure. But it would be cool to know other peoples learning experiences.
