I am not sure if I will also be around after a decade but it is said that time is likely the safest speculation that Bitcoin will hit a million dollars.
But we do not know how this cycles that keep on changing every time we are on it. It might be quicker for the next few years and cycles to come and we might get too close to it.
I'll hold but I won't miss to sell because that's how it should go and we have to enjoy taking profits.
You still can't guarantee it because we already experienced it, before no one is expecting that the current Bitcoin price we have right now is what we will experience.
Bitcoin is unexpected so we must be always prepared.
We need to consider a lot of things now especially since we already have a lot of volume, a lot of people already know Bitcoin, etc.
