If you follow ETF flows, you will see that they were even willing to buy when bitcoin price crossed $100k and I think they know what they are doing. Not to mention, there have been many lessons learned in the past. Many people thought that bitcoin price was too high and not worth buying when bitcoin reached $10k, $20k or $50k but surely most of them are regretting it now. So I disagree saying that the current price is too high.
Bitcoin is unpredictable, many people are worried that the price of bitcoin will drop to $60k in the next few months but don't forget that the opposite can also happen. Bitcoin could also rise to $150k or $200k before correcting, and there is also no guarantee that the price will drop below $90k again. So, instead of procrastinating, why don't we use the DCA strategy and start buying now?
Considering these whales know what they are doing, and how bitcoin will grow on the long run, we have to realize that people and companies who buy Bitcoin ETF, are the ones who do not need it for a decade or two. We are seeing something bigger here, if you can buy bitcoin and can wait for 20 years, of course you will get richer, you know it and I know it and everyone else knows it.
But when you are a regular person like us, we may need it due to emergency issues, whereas when we are dealing with companies this size, they do not like get sick and need to pay medical bills, they are already rich, either they keep it, or they are in a bad situation to get bankrupted like 2009 which saves them anyway and they do fine. This is why there is no worries about this at all.
