After this round of Bull Market, mindless Coin Hoarding may no longer be recognized. It used to be easy to get rich by simply Coin Hoarding, because there were fewer choices and fewer coins in the past. Now, facing hundreds or thousands of coins on exchanges, one must learn to choose and engage in swing trading. Set the golden ratio based on the rise and fall of coins, sell when it rises long, buy when it falls long. Believers may become losers, while skilled swing traders can stand invincible.
