And while those who owned Bitcoin before October 2023 may feel like winner right now, but it does not mean that it is too late for others,
For sure there are levels.
There are guys who just got started around October 2023 or even a year prior to October 2023, and there are guys who had already pretty much established their bitcoin position prior to October 2023, and there are guys who started accumulating their bitcoin after October 2023, including guys who are just starting right now.
Anyone who has no bitcoin is not prepared for up.
Anyone who has low amounts of bitcoin may well be insufficiently/inadequately prepared for up.
Guys have to make these determinations and frequently they make mistakes in their failure/refusal to get started at whatever the BTC price happens to be.
You are right that not everyone started at the same time; some started before October 2023, others around that time, and still others are only now learning about Bitcoin.
If someone does not own Bitcoin, they may miss out in the future if the price increases. And if they just have a small amount, it may not make any difference for them; this is why it is so important to get started, even with a little amount. Waiting too long or being afraid to buy will only make it more challenging later.
So it's up to each person to choose when to start. But the earlier you start, the more prepared you will be when the price rises.
Bitcoin is a long term journey, you may not see big profits in one or two years, but with patience and consistency, the reward will come later, so instead of looking back and regretting, focus on how to build your investment for the future. Continue building, stay humble, and always plan. That's how you win in the long term.
Even the past examples do not really seem to show great levels of wealth creation until much time has passed, and surely it does help to experience 70x or greater BTC price appreciation after a guy had already done most of his buying.. but yeah, not easy to get into such a position... so guys likely need to just stack what they can at the time that they learn about bitcoin.. and keep on stacking, as you mentioned.
Sure, Bitcoin does not make people rich immediately. it normally takes years of holding and buying gradually; such big 70x returns are usually achieved by those who started early and continued to buy before the price increased.
However, it is not always simple to get started early or to know when the right time is, so after someone understands what Bitcoin is, the best thing to do is to keep buying whenever they can. And over time, something will add up. If a person did not start early, it is better to start now than wait forever.
