Yes, but I think it would be better to be more patient to buy, because a sharp decline does not guarantee that for the following days it will rise quickly. In the near future I still believe the decline will still occur so yes, this period I don't think is the perfect time to buy. But if the price is in the 40k-45k range then I think that would be the best time, just to anticipate a sharper drop and consider the ATH value.
It does guarantee that it will go up, it just doesn't guarantee that it will go up right away, so the guaranteed part is "it will go up" but that's it, it doesn't say if it will go down more now, if it will go up right away, if it will go down to 10k, or if it goes up to 100k, there is absolutely ZERO information about what is going to happen, only thing 100% known right now would be price will go up in the future for sure, and that is where we are right now, it is down now and it will go up again, which is why there are plenty of people buying as well.
Why do you think price dropped 10k+ and not dropped more? Because people realized since it dropped, there is absolutely nothing at all that would be hurting our situation as long as we can wait enough, which is why I believe there is a situation at hand where we could potentially do better and get bigger only if we work together.
