When asked, people will definitely say that bitcoin is both a spending tool and a long-term saving tool. But in reality, I believe anyone who owns bitcoin has the same purpose as you, which is to use it as a long-term savings plan instead of spending, including me.
Indeed, we, the bitcoin users, are limiting the scope of bitcoin usage and we only use it as an investment. We never intended to use it for its original purpose.
The truth is that Bitcoin was designed to be a currency but today it is only used as an investment. No one wants to use it for its original purpose.
When just started or in early phase of your investment and portfolio building, bitcoin accumulation, you will not want to sell your bitcoins. With time, your portfolio becomes bigger, and you also get profit from it (at least on paper before you cash it out), and your finance becomes better, you will have need of spending your bitcoins or cashing it out.
It comes to time for thinking of and even practicing DCA withdrawals.
