I am not investing Bitcoin at its ATH but the reason I still could is that I believe in Bitcoin. Of course we will experience the bear market someday but over the long run, I don’t think the bear market can do any harm because Bitcoin will worth a lot more than it is today. Maybe $300k, $500k or even $1M. With or without the ETF.

I don't think they have any knowledge, most people are still scared of the bear without knowing its the right time to invest in bitcoin, FOMO I'd just the feeling, no one wants to miss out but your here at such a wrong time, we could as well be at the peak of the bull and your just coming.
But it's not too late I guess, although it's been quite since Monday, bitcoin still have enough power to break into 100k
Maybe after the halving.

If bitcoin has shown positive tremendous effect within its first decade, then most probably the effect will be a lot huge and bigger within in the next years starting today. This is the reason why I’ve been hodling bitcoin and continue to DCA with bitcoin even at its ATH. I have bigger faith that bitcoin price will create no limits and will offer a lot of new opportunities to those who have high hopes with bitcoin.

Despite of its new innovation that it brought to us, bitcoin has always been in high demand due to its huge promising profits. And most likely that’s what motivated us to keep going with bitcoin, mainly for profits, and having those convenience brought by bitcoin are just a bonus.

Some of the people's continue to invest in Bitcoin because they know that that it will eventually continue to raise, even after it has hits the ATH. Everyone is optimistic about Bitcoin's ability to increase even after the record high is broken. In fact, some people will have enough money at this point to invest in Bitcoin. They don't care if Bitcoin keeps rising, and I don't blame them—everyone has a different strategy for making investments that they hope will yield significant returns in the future. However, those who have already amassed a sizable sum of money against Bitcoin are the ones that prefer investing in it when it is growing up.

The circumstances of everyone are different, so those that were able to only get the money they needed to invest in bitcoin now have my sympathy, as they literally could not pick a better moment than now to invest in it, but all of those that were on the fences about bitcoin and refused to invest in it when it was much cheaper and are just doing it now, have no excuse in my eyes, as even if I believe they can make a lot of money, they could have made way more money if they just were resolute enough to invest in bitcoin when it was close to its bottom.

From my perspective, I think most people buying/investing in Bitcoin even at this levels is because of the believe that Bitcoin will continue to rise, even if there will be a price correction it doesn't matter because it will surely rise to good level where profit will be made.

Another reason why some people like me are stilling investing in Bitcoin is because we know some invest strategy that is a very much recommended one for everyone which is DCA. if anyone here uses the DCA method and/or strategy to invest Bitcoin he or she would continue to buy regardless of the current price and this is an act that is been driven by a target of long term investment. for me personally as long as Bitcoin has not reach its peak in still buying especially if I have the capital to buy then I will keep buy and holding because Bitcoin as a paradigm has not seize to amaze me ever since know.

Aiming for a higher market price and investing mainly for long term, plus we have good things that obviously get the Bitcoin a big boost like the ETF.

For sure in the coming months, we are going to get the correction, even though we could see the market price skyrocket right now up to 72k$ which is already a new all-time high, for those experience trader we know that a correction is surely going to hit soon, and there was no other way around it if the market price continues to skyrocket we are going to get a correction soon it's just inevitable and part of the market cycle. Mainly I'm just doing it for profit for sure because aiming higher is going to give me a higher profit than just selling now around 72k$, I mean if I sold my Bitcoin if the market price is around 150k$ it would be x2 of that profit.

It's not really just what motivates me, but I think it is about because I can hold it, what I mean here is I dont really need the money right now since I already have the financial foundation, I have a full-time job, and a good side hustle which I could use on my needs, wants and pay the bills, etc. I dont really rely on my Bitcoin investment as an income I mean it's an investment in the first place so it should have been for long-term things. Still, I'm aware of the risk of Cryptocurrency so I do sell some of my Bitcoin like when it hits 72k$ but it is just a very small percentage, it just goes straight to my savings waiting for another opportunity so that I can reinvest it in case the correction hit.

I mean if you doesnt have other sources of income other than your investment it is surely going to be tempting to sell especially because the market price already hit its all time high, and i wouldn't really say that its a wrong move because you already make a good profit on it, but in my case I can hold it for long term and Im aiming for a higher market price it wasn't really because I'm greedy but still I want to see how its going to play out, I have a lot of room for profit so even if the market price drop to a very low price I know that there will be another cycle.

lol ,without ETF it may reach that high but slower than if there is ETF and why need to call that out when we are enjoying our bullrun because of Bitcoin spot ETF.

and have you invested now? because for now I decline my buying because it is almost 74k$ and that is so much risk and capital need to put in.

My thoughts are that based on just US ETF inflows since January, my mental math says they alone are collecting about 8 X new supply at US$72000, per week.  And so 16 X new supply post halving.  That would mean equilibrium is 8-16 X the price now, assuming ETF demand stays constant.  That doesn't include other non-ETF demand which is more difficult to measure.  So once those willing to sell at each price level dries up the price has to increase to get anyone else to sell.

You'd think people would clue in that even ignoring the halving the supply/demand curve seems to be way out of whack and they should remove their coins from the market, but I guess not yet.  Prices are set at the margin so it doesn't take much more demand or slightly less available supply to significantly increase the fiat price which is why we are seeing right now.

So that is why smart people are still investing.  Of course we've been hearing "tulips" and "bubble" and the same nonsense for 14-15 years so there are plenty of people who don't seem to have clued in or are purposefully carrying water for the fiat-inflation-loving statists.
