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
