Really hard to answer mate as we don't know what will be the top price of bitcoin. But honestly, I dumped it when the price is around $18,000-$19,000 so I think I will sell it if I think that the price of bitcoin has reach floor price. I just lucky that I was able to sell some at those price because it plummeted after that. But to answer you, I think I might sell again if it reaches $40,000-$50,000. I will hold what I have right now, I already bought back bitcoin again during its dips around $12,xxx as well. Holding is more of mental, its really hard not to sell if you are seeing that your investment is growing. I just sold some of stash for the holidays just like anybody else. LOL. But you have set the bar high, I don't know if you have that mental toughness to hold until it surpasses $250,000. But each one of us has different strategy. So goodluck holding your bitcoin until it reaches your price goal.
