The longer the years, the longer we hope for Bitcoin to reach a huge price. If you know about this process, you will feel less worried about when Bitcoin will reach $1 million.
As a Bitcoin investor, I am confident that Bitcoin will reach any huge price we have in mind. Before then, we will see Bitcoin reaching a reasonable price from the current ATH price we have had. For example, if Bitcoin's ATH is $250k, the next ATH may be $500k, then $750k, before $1 million. All these speculated prices would take many years to happen
In this life, I've learned that anything is possible. So even if right now, it is quite far in the horizon, never say never. It is possible but we don't know when. Just have conservative estimates because you are using your funds that you have no idea when you will get your target profits.
