I am not surprised because, at every point in time, there are people who still doubt Bitcoin unless they see proof. At 50k those set of people have been procrastinating now the price of Bitcoin has hit 90k they still can't buy because they're still in doubt since they do not want to put in their money now and then it starts falling down. Like I have said before, no matter what the price would be, there will be people who will never buy at all. They are short sited that is why think only for short term purpose. And another thing is that they do not belive, they only care to invest in Bitcoin because of some investors who preaching the benefit. Deep down they are scared of investing, since they fail to learn about Bitcoin. To overcome the FOMO, an investors need to first learn about Bitcoin and how to invest in it.
The thing is, there are people that can't convince themselves in doing what's needful, no matter what you tell them they always feel that they need to wait more to see if there will either be a negativity or positivity on the said investment before they can decide on what to do, this kind of persons end up regretting their actions when things turn out to be good, Buddy you are just factual, when Bitcoin price was $10k or less some persons had the money to buy but was full of doubt, some people had the opportunity to buy lower than the amount I mentioned, today many people are regretting their actions but though it's not late hence Bitcoin is a long-term investment and we are looking at a new ATH by the end of this year i think one can also start now if really they are interested.
for the skeptics, there's always a reason to point at as to why they shouldn't buy Bitcoin at certain time. You just have to understand that one attribute of procrastinators and skeptical persons is that they are good with giving excuses.
When Bitcoin was down they will have the mentality that it's possible that Bitcoin can't go up again and now that's it's high and has gotten to a new ATH, ask them and they will tell you that had it been they knew, they should have bought earlier when Bitcoin hasn't gotten to this price.
Truth is that there's always no time that is the best time to buy Bitcoin. It's just like the statement that says, whichever time you've woken up is your morning, it's same with Bitcoin. Whatever price you come to witness bitcoin at should be the price you should buy Bitcoin. Don't regret that if you had known earlier you would have bought more or try to wait for Bitcoin to dip before buying. Those are all waste of time that will cost one to regret later in the Future. From what's happening, continuous waiting for bitcoin to DIP before buying will take us to $100k and then $100k and so on and then you will have enough reasons why shouldn't buy. Refusal to buy will keep you at a spectators spot so you just make comment on Bitcoin price without actually enjoying the benefit of any future bull.
