The 200u challenge reached 10,000u. Originally, I had been making small profits, and my balance reached 430u. However, yesterday I blew up my account twice, leaving me with only 20u. With the market being so poor yesterday, I didn't know what to do with that 20u. Fortunately, I opened the event contract and saw that I could earn just by betting on the rise and fall, and the profits were high. It was even easier than buying contracts, and the returns were greater. With a mindset of losing everything, I decided to give it a try. I bought 6 times in the beginning and hit 5 times, which felt pretty good. I didn't expect to end up earning back 800u in the end. My current balance is now 820u.
