I received another beautiful limited-edition pizza festival gift box from OKX. Looks like I have enough BTC this year, three times more than in previous years, haha... As for when I bought my first BTC, I don't quite remember since it was a small, piecemeal purchase. The exact purchase record I can find on my computer is August 10, 2018. I bought a total of 43.37 BTC at an average price of ¥45,938; and 100 ETH at an average price of ¥4,272. The units are RMB, not USD. Back then, my understanding was limited, and I thought it was so expensive that I didn't buy many. Now, even if you change the unit to "US dollars," I still think it's incredibly cheap... #OKXPizzaDay
