Maybe it might get to it slower or faster than most persons anticipate but it doesn't stop it from happening. But like it's been said countless numbers of times, it's not just about waiting and anticipating Bitcoin to hit $100k that matters, it's more of buying and building a good portfolio before it even gets to that price that matters the most.
One thing is certain about bitcoin, when a lot of people are preparing now to buy bitcoin at this price before it gets to $100K, that 100K may be the starting point of accumulation of others. Some users may see the opportunity now but because they don’t have the financial resources to put into it, they may miss buying more bitcoin now and can only get to buy more when the price have gone high. Some may just get to know about bitcoin, show interest in it at that time and start their accumulation at that time and will still be hoping bitcoin goes to $200K before they’ll think of selling them.
Bitcoin accumulation has now become more like a trend and with its unending demand, it may continue to move in the upward direction and breaking all time high after every cycle. The DCA strategy is good and very easy to start and as much as good as it is, some people may not still be able to buy now until the price is up than this and those financial status changes that they can spare some money to start accumulation. Opportunities in bitcoin is showing to be infinite because of how it has transgress from inception till now, so starting now or starting later without inconveniencing yourself is still okay.
I don't see any reason to put any kind of a price in which a person might buy or sell bitcoin, since there should be quite bit of uncertainty regarding bitcoin's growth in the next 20-30 years or more, and some investors are likely coming to bitcoin young, and yeah there are also older investors too, so that is part of the reason that many of us suggest at least a 4 year investment timeline, but that 4-year minimum timeline might be more for the older investor, since a young person might spend 4-10 years or longer just accumulating bitcoin before potentially getting to an BTC accumulation stage in his investment where he might start to consider if he might transition into some other kind of a stage, which well might be maintenance and holding prior to transitioning into a stage that selling might start to become start of the practice.
So it seems a bit short sighted to just proclaim that sales will start to take place in the $200ks when there might hardly be any clue in regards to how many coins might have had been accumulated, and even if selling is a good idea, at least not selling in large amounts but maybe sustainable price based and/or even time-based selling strategies might be more reasonably within contemplations but even contemplating selling might not be in order to get out of bitcoin, since who is going to want to spend 4-10 years or longer building up his bitcoin holdings and then potentially end up in some inferior investments or some inferior consumption good... when there could be ways to consume and/or to invest into other things without making any large sales of bitcoin holdings...so yeah, each person has to decide the contents of his investment portfolio, including if bitcoin is in there and also including ways to have cashflows that may or may not end up coming from the bitcoin holdings.
