So, you bought a house for $1m and a year later someone offers you $900k for it. Will you sell it? Why should you? If you're not in debt, have money to pay your bills, you won't sell it, right?
another scenario is buying this house for a million then someone offering $1.2 million yes you have made profit but is $200k really the best profit you can make? just because the price has already gone up means you should immediately jump the ship and sell it especially that there is a big chance that the price is still gonna rise up if you could just wait for a little bit
be patient and do not be impulsive do not get too excited and always look at the bigger picture
This is an interesting approach.
Surely time matters in this case. If This was me and I got a house for 1mill and then someone a month later offered me 1.2, I'd probably take it, unless that exact house was somehow important to me.
For example I could have a family member who lived there 50 years ago and then it changed hands until I was able to purchase it, or it belonged to my idol, or my father who passed away built it for someone, so there's his actual sweat embedded in its walls.
As you can see there's a lot to consider.
On the other hand, if they offered me 1.2mill 20 years later, with inflation being 5% a year, I'd probably not agree to it... unless:
-I needed money
-I needed to move anyway
-I couldn't find a better offer
-the house needed work, or had some issues like mold
And so on
With bitcoin there's no such problems. It exists. 10 years from now it's going to be the same protocol, the same blockchain. With fiat inflation and bitcoin's scarcity in mind, I'd expect at least 10% a year steady growth, so if I was asked without being able to check the price if I'd sell bitcoin for $100k 10 years from now, I'd say no.
