Title says it all (I know, shitpost). Pick any single day/year in the future you'd choose to view the price of Bitcoin and why.
If the price is moon, do you drastically change your current lifestyle? If the price is way down, do you sell right now?
I believe this is a good Hodling indicator. My Day would be Jan 1st 2021. Some time after the next Halving and what I expect to be global financial turmoil. If it were $25k per, I'd quite my job right now and spend time with my family. This day is the soonest I plan to sell.
