The best advice given to me by a friend who was in early on crypto was to not focus on what the potential future worth was going to be, but instead to think about the goals that you had in mind for the value of the assets. If it was retirement, then just don't touch and don't look... For him, it was to buy a house and maybe start investing in other property, and so when he was over that mark he sold out (with enough leftover staying in crypto) and did what he wanted and got a house. He's happy and not obsessed about the potential ups and downs of the market!
