As an old investor who started to get involved in the B-circle from fil storage mining, I have seen the transformation from ok platform to okx, the highs and lows of fil and eos, the waterfall-like decline of Luna, and the loss of wallets in the primary market. Many friends in the currency circle have continued to do business, and some continue to pay attention to digital currencies. Since I am an old investor, I have seen many lows and have become more cautious about the rapid rise. From 300 BNB to now, it is enough to have an extra income a month. There are too many big names in this circle. Don't be greedy for getting rich quickly. It is the hard truth to walk steadily and keep gaining and keep your heart.
