Bitcoin give more profit for investor that started accumulating very early when the price was low. Some Bitcoin investors prefer to wait until when the bull market is coming close that's when they will begin to rush and invest so that they will not miss the profit when the price begin to pump.
If Mr X bought his Bitcoin in 2022 for $20, 000 for 1 Bitcoin and Mr F buys his Bitcoin today that 1 Bitcoin is trading for $42,113, who will make more profit when the bull market starts? If bull market starts, the people that bought Bitcoin when the price was very low will make more profit than people that bought today.
Always Start accumulation very early, don't wait until when bull market is close before investing.
Everyone will say that, because it is already a fact that the price of Bitcoin used to be only $1, now it is $70k, even if you knew this day would happen when Bitcoin was launched, I'm sure you would have bought a lot of Bitcoin when it appeared, no one would have paid much attention to it.
OK, because this is already expensive, so I think this will still be considered a cheap price for the next 8 years. It seems so, because it is likely that many people are speculating that the price of BTC will reach above $100k, some even say it will be higher than $150k. Whether that will happen or not, it is certain that now you can still accumulate BTC as you said.
