I would not have enough capital to buy enough Bitcoin even at a cheap price. Let alone think about mining, which certainly requires enough initial capital.
The only moment I might want to repeat is when I had enough ETH that I was forced to sell to buy computer equipment for work purposes. Even though it was also a necessity, I quite regret selling the ETH I had at a price far from the current price.
The situation might not be much different if I had Bitcoin than ETH. If what was repeated was not only time but also a better financial situation, of course, the situation in maintaining Bitcoin and other assets would be different.
