It is possible by relating past cycles that we are about to start a movement full of green candles, so we have to see if it is time to enter, personally I prefer to average high instead of missing the movement, since even for the best analysts or traders it is very difficult to buy at lows and sell at highs, so leave the first and last dollars to others.
Since we are reaching 10% of this cycle, since this year that was the halving on April 22, and the orange lines indicate where bitcoin was in the past cycles right at the current moment since the halving, so really looking at the past two cycles, we should not consider falls to 47,45,42,35; of course nothing is impossible to happen, but it would be the first time in years.
So in my opinion it is better to get on the movement before staying down waiting for purchase levels that may never come; I also want to say that you should keep 20% of liquidity in case we lose the 50$BTC and I am wrong.
But statistically and looking at the past, I really don't think it will happen.
