It's too young for me to retire because I'm not even three years old. $1 million is a fantastic price that is beyond my mind if I own a few BTCs. Honestly, I can't imagine what I could do if I had a few Bitcoins that cost $1 million per BTC.
For now with what I have in mind, I wouldn't choose retirement.
OP doesn't understand that even if Bitcoin reaches $1 million, it is not enough to make someone with a family to care for retire too early. Bitcoin to $1 million won't change a thing, what matters is how much Bitcoin in holding, as of now the price of Bitcoin is far huge for many to accumulate 1 Bitcoin equivalent to $100K then hold long enough when the price of Bitcoin will top $1 million in value which is 10X of what was invested.
Before retirement requires proper planning, and Bitcoin should only be part of the plan and not the whole plan.
Actually, it's not that you don't understand, it's just that your understanding is different from yours in interpreting retirement preparation.
Obviously if we have a lot of Bitcoin and the price can reach $1 million, it will make the owner rich when they release it. The question that will arise when you sell it for $1 million is what will you do? Business? That means not retired but still working. So what if the business goes bankrupt?
Well. Therefore, it is better if you continue to be a Bitcoin holder even though it is time to retire.
