In 2014, I sold 30 BTC and started my crypto adventure. In the same year, I learned for the first time how crazy ICOs can be. Two years later, I experienced 94, went overseas with exchanges, witnessed the rise of Binance, Fcoin trading and mining, and in a blink of an eye, 2019-early 2020 I got to know DeFi and Compound liquidity mining, and then entered DeFi Summer, NFT Summer, the Metaverse, and the door to the new world opened, with gold everywhere, and finally found that it was not easy to buy back the 30 BTC that year.
