I couldn't put the full title in the subject line due to character restrictions, but here is the full question:
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?
The market isn't always up, and when it's consistent on a specific value, using it as an asset for the transaction won't affect you much if and only if you've bought back at the same price. The OP makes sense, I understand the point, and I'm wondering why I'm still using my BTC for other things if it'll just go up. Taking profit, on the other hand, should explain why others continue to sell and use bitcoin for transactions, we have different approach on crypto, can't blame them if they're happy and satisfied on what they're doing.
