I entered the market in 2021 and bought altcoins, turning twenty thousand yuan into five hundred, and it hasn't recovered since. Later, I invested in BNB at a high point and didn't sell, going from over 600 to just over 200. In 2022, I invested another five thousand in Dogecoin contracts, turning it into twelve thousand five hundred. Later, I encountered the FTX collapse while trading FIL contracts and lost everything. Starting from 2023, I began dollar-cost averaging into MC, investing a total of only ten thousand, and encountered the MC upgrade to BEAMX, turning it into twenty-five thousand and buying 14 BNB. Later, I invested another ten thousand to buy 6 BNB, and it has tripled since then.
