To me I actually think that having an investment goal is quite appropriate because as common man that just want to secure his or her future true Bitcoin, he just have to accumulate Bitcoin true the DCA method still he is satisfied with his or her current holdings, so when that target is met, the next question he should be asking himself is when is he willing to sell, like the numbers of years he is willing to hold or the amount he would be selling if the price of the asset in his possession reach that particular amount, so to me, investment goal should be made a priority, like if you are buying Bitcoin for retirement purpose, it's still good, as long as you have a specific goal in mind, because not having a specific goal in mind sometimes makes you act confused concerning your investment sometimes, because you don't have a specific vision before investing.
Before investing in Bitcoin we need to have a specific goal and plan. For example suppose many people invest in such a way that they want to invest weekly or deposit bitcoins and there are many people who want to deposit bitcoins monthly even their amount of money is different. Everyone's Bitcoin investment plan is different, some may want to deposit more bitcoins and some may deposit less bitcoins. I think those who don't have a specific goal or plan about their investments are either haphazard and can break or sell their investments at any time.
So before we invest we need to focus the goal and set a specific time frame for how many years we will hold our investment and accumulate bitcoins accordingly.
