One thing I have realized of is the fact that Bitcoin price is unpredictable and waiting for a certain period or cycle may sometimes be fruitless waiting and the next bull run can happen at any time.
So the best thing to do is to always prepare ahead and hold more Bitcoin because you never can tell when the next market turn will happen.
You are right. First of all, the current price has fallen below the price of the last round of bull market, and the risk factor has been greatly reduced. The most important thing is how much BTC you hold.
