Yes as long as Bitcoin investment is concern we don't only need to hold and wait but we should just keep on accumulating more and more Bitcoin until we are satisfied with the quantity of Bitcoin we have accumulated not in less than 3 years below but 4,5 years and above, we can buy more Bitcoin using both DCA method and the lump sum strategy which will help us accumulate more Bitcoin in a long run.
Am not sure of qwhat you meant by being
satisfied, nor do I think other investors who consider the future would use such word. I am very sure that no one is ever satisfied with making more money (even the world's richest people), so why should we be satisfied with making investments?. The continuous use of the DCA strategy for at least four years, before doing whatever you want to do with it doesn't mean someone is satisfied. There might just be a very important project that has been sidelined, with the intention of making use of the investment after at least four years.
In another sense, if your portfolio happens to be very high, but you keep getting extra personal funds, then you should continue to invest. Or do you prefer to waste your extra funds just because you feel your accumulation portfolio is satisfactory enough?.
There is definitely a point of satisfaction in whatever we are doing in life and bitcoin investment is not exceptional. There is a point you will get to in the course of your investment and you will feel that wow, I have accumulated this amount of bitcoin, I think I'm satisfied with what I have so far. At this point that's when you think of diversification. I think that's what @Zack5000 meant when he used the word satisfied. If you have gotten to this level, you can channel the extra money that's coming your way into construction, Transportation or any other business you deem fit.
Not that you are satisfied with making money rather you want to get into other forms of investments. Let take Elon musk as an example, he invested in bitcoin, Tesla, X (Formerly known as Twitter) internet service (Star link) he has positioned himself very well and profits are coming from different angles.
Judging by what you are saying that one shouldn't be satisfied with bitcoin investment, Elon musk should have sold off his other assets and only focus in bitcoin investment. So it's not wrong for someone to say he/she has gotten to a point where they feels satisfied with their bitcoin portfolio and seek other avenues to diversify their investments. Even in economics portfolio diversification is very important, so don't be confused when you hear people say they are satisfied with their bitcoin portfolio. It doesn't mean they are tired of making money.
