But yeah, they might be in a worse situation if they come to bitcoin at $80k, and then they have to consider whether the BTC price is going to dip or not. .and if so when? There is no guarantee that BTC prices will dip back past $80k once they go above that.. so people coming to bitcoin at that time ($80k and other various points) do have some potential dilemmas regarding whether to wait or to get started right away.. and if they get started right away, then by how much?
Anyone who gets in when BTC get to $80k may not actually be making the best decision. BTC ATH is about $69k and from history, next bull run will surpass this with target at $100k. As usual, we will see some corrections when we hit this new ATH. Since BTC has the ability to correct even beyond 20%, it might go below $80k again when that happens and anyone waiting to enter at that price will be at a temporary loss and might panic and sell.
I think the best is to buy anywhere below the current ATH of $69k...even now.
Yeah, but you are fighting with the hypothetical, because in this hypothetical the BTC price is already $80k and a newbie is coming to BTC and he is having to decide what to do at that time. He cannot go back in history.
Another thing, is your presumption that BTC will dip merely because it gets to $80k. That has not always been the case in BTC history, but still we cannot necessarily merely use BTC price history in order to make our decision about what to do. We have to decide right at that time what to do, and we are new to bitcoin, we do not have any and we have to decide.
If you decide to wait for the dip, then you still don't have any BTC if the price does not end up dipping as you are suggesting that you expect it to do so.
