In this wolf-like cryptocurrency market, small capital wants to grow big. There are only two choices; either roll over or compound interest. Many big names in the stock market dare to heavily invest to achieve hundredfold or thousandfold returns.
Heavy investment and aggressive actions, at critical points, require courage that is not reckless gambling, but rather a well-thought-out plan and risk control, daring to heavily invest at high probability moments.
This is why others can achieve A8, A9 after just one or two rounds of a bull market!
