Holders of Bitcoins can certainly get the ATH of Bitcoin as well as the DIP. But finding the Bitcoin Deep is truly a matter of luck for many. To be a Bitcoin holder it's not how much investment he has, I think it's how much he believes in Bitcoin that is the matter.
if you had changed the last part of your statement, maybe you should have made a little sense but what you said here, you've not made the right statement.
Believing in Bitcoin is good but what's the essence of believing in Bitcoin without having much investment? How much investment you have is very important and it's absolutely more importantly than what you believe. That you have investment much into Bitcoin suggests that you believe in Bitcoin and what you're trying to say in the religion sense could be compared to mere having faith without putting in the needed work. Just like faith without work is dead, having a strong believe and hope in Bitcoin without investing much into Bitcoin is literally waste of knowledge, fake believe and wouldn't do you any good.
I understand what you mean @Hewlet, but I think that Rabata is also right too. This is. Ecause it is when you believe in bitcoin that it can be a safe haven tomorrow, or that you can use it to turn your future around that will enable to hodli for a very long time, or even use it as part of your life. Now there are two scenario for you to look into.
The early investors, Mr A was opportune to buy bitcoin for as low as $100, because he did not understand the potential of bitcoin, and much believe in it, but he was able to buy 10BTC at that time. As time passes by he saw that bitcoin price is increasing with time line, and he sold when bitcoin was $1000, believing that he have hit the jackpot, forgetting that for bitcoin price to reach 1000k, that bitcoin is capable of reaching $10000 and higher, because he didn't have the strong believe in bitcoin, currently such investor will be regretting that he sold too quick. Same happens to people who see bitcoin as something that is worth hodling for short periods of time like 4yrs and they sell off to take profit. He don't believe in the future of bitcoin if not they will hodli for a longer time.
Now Mr B, also bought 10BTC when bitcoin price was $100,because he sees bitcoin as a very precious investment, because he believes that bitcoin price will be more valuable in future, and when bitcoin price was 1000k he didn't sell any bitcoin but rather continue holdi because he believes that for bitcoin to reach that high price, in future bitcoin can hit 100k price. No matter the challenges that Mr B has passed through based on FUD, FOMO. He was still strong enough to overcome them and hodli because he believes in bitcoin.
It is when you believe in bitcoin that you can be able to increase your bitcoin size and hodli for a very long time. Laszlo would not use 10000BTC to pay 2 papa John's pizza.
