Well, the other option is hodling Bitcoin and hoping that it will grow more and more and you can not only retire but live luxurious life off it. But I think the risk/reward ratio suggests that it's better to retire asap by taking Bitcoin profits and reinvesting them in safe assets. Because just as Bitcoin can go to millions, it could also crash to the ground, and that would be catastrophic for someone who planned to retire with Bitcoin gains - now they would have to start from scratch.
I don't know why people put much of their earning or savings in bitcoin hoping that the price will skyrocket just like that, if your are oppo tuned to get a profit in bitcoin just try to do other things which you have stated here, with circumstances soruinding bitcoin itself I was meant to know that it's better if we invest what we can afford to lose, I hear this everytime I want to invest, the inventor of bitcoin never gave assurance that when you invest you will be profiting without losing, with this idea we should know that bitcoin can profit you and can still make you poor, I didn't say that we shouldn't hold but before we do that we should think twice.
