Now people are more educated regarding crypto. So if they invest into crypto means crypto is drawing attention. People are greedy and they bought btc at insane price. It also happened to other stocks. May be this will not happen easily in future. But btc will grow and we expect btc to be ATH in future for the potential. No hype, no bubble just pure tech.
So you want people to invest on bitcoin so that it can easily reach the all time high once again? Aren't "you" being the greedy one?
Statements like your are what discourages people from buying bitcoin. If the price is high, according to you, we shouldn't invest because that is "insane" price? Then how would you expect the price to increase further? How do you expect people to enter the market when the price is high?
There's nothing wrong with what particular range of time you invest, even they invested on a time where it is high, it's fine as long as BTC is still growing and they're gaining profit on it.
People's investment isn't the key to a new ATH, if you want to grow your own BTC, better do trading than forcing other people to adopt the usage of BTC for a new ATH. No one can predict when a new ATH will happen, well there's a lot of factors to consider but it's just minimal and prices are still unpredictable.
it is nearly impossible to reach another ATH because the actual value of BTC is not increasing, it is just an effect made by its holders, but now there are many coins and better alternatives, the only 3 features of btc, it was the first, it has the high market cap and how many people, and platforms accepting it. otherwise, any other coin will have a certain purpose, unlike the general BTC.
