I'm not going to wait until precise marks anymore like 100,000$ or 250,000$. I did it last time expecting bitcoin would reach 100.000$, and it ended hiting 69,000$ and crashing next. Now I will just wait for the next bull run. Where it leads us it's ok for me and then I'm going to sell my holdings. I have to invest in another sectors of my life and can't hold bitcoin forever without putting it into good use. And to be frankly, it doesn't make sense to hold money forever. At some point you have to use it, otherwise why do we start holding at first place?
This is the ultimate goal of making a profit and if OP can wait for this price without a specific date, then it is good for OP.
I don't think hoarding too much time will get you satisfied when the price doubles or much better triples from the capital but for sure --it should be an amount that you can afford to wait. You can sell at any time as long as you have your profit or never sell under the price that you have purchased. We can also set a goal of taking profit/ROI but if you want it to make double, it could be but you need to wait for it.
For me? I will sell for as long as I needed but not in a losing position.
