We buy something like bitcoin by knowing that we can sell it in future.
Buying and selling is a pair that supports each other and if there is no seller, we can not be a buyer to purchase bitcoin. If I bought bitcoin, I hope that I can sell it when I need money in future, and I will never buy bitcoin if I know that I will not be able or struggle to sell it in future.
When I need to sell bitcoin, I won't hesitate to do this and I won't regret about this. If I plan to not sell my bitcoin, I would have reserve my money in cash for using and making sure that I won't sell bitcoin in my Bitcoin portfolio.
For me it really comes down to personal strategy and goals. Holding bitcoin long-term can be a solid investment play but spending it occasionally also supports the ecosystem and reminds us that it's not just an asset but a currency too. In the end whether we spend or hold the most important thing is making decisions that align with our financial plans & lifestyle.
