Bitcoin is not an investment. It is money (not a currency). Money is a currency that can also be store of value (fiat is currency). To be SoV bitcoin needs to have a capped supply hence the 21 million cap.
People can use bitcoin in many ways, money, currency, SoV and because of its multiple use cases, it confuses people to define what it is and what it is used for.
With me, I don't care about it too much because I know Bitcoin is available to use for many things and more important if I can invest in bitcoin, hold it, I can get richer. Use it as money or currency, I can do it some times in my life but it's not my main concern with my bitcoin.
If I can turn myself to Bitcoin investor newbie, to a holder, I can get richer passively with bitcoin I am holding. 4 years or 5 years of holding is not big problem with me.
