It's nearly impossible to go through each comment so if someone has already answered it, sorry to repeat it.
If bitcoin was fully adopted into everyday life, why would it ever be used for day-to-day transactions if the general consensus was that the price would always appreciate?
Because, bitcoin doesn't exist in isolation. There are hundreds of crypto which are even more profitable and yeah bitcoins won't be probably used for daily transactions because you want to save them but surely there will be traders. In fact, if bitcoin is not used for small transactions that's great news because that reduces the transaction cost and more coins for everyone technically.
We all know the price of properties (or land) will usually go higher, right? Yet there are sellers and buyers in abundance.
