This is what must be emphasized, While I wouldn't say that waiting is a mistake because there are still many people who are trying to buy on the dip
Waiting is a mistake if you have no coins or if you are a low coiner. If you bought a decent amount of coins, then you are prepared for up, if you have not bought much or any coins, then you are ONLY prepared for down if you are waiting, which down may or may not happen. So you are gambling and that seems like a mistake to me.
but in the end when we focus on DCA in the end everything becomes different where our focus can lead to buying regardless of the price because our goal is long-term not short-term so while we can afford to buy then why not because it's not wrong to start by buying now even if there is a decline again rather than we are the ones left behind because bitcoin is more unreachable for their size because they think it is too expensive so it will be more worth it to start early while waiting and convincing them to buy it.
We cannot turn back the clock, so we have to decide from now.. are we buying or not?
Yeah, sure it would have been better to have had bought yesterday, but we have to decide from today whether we are buying or not and whether we are sufficiently prepared for up with the amount that we already bought.
It is also wrong to start by buying now even though there is a decline back than we are the ones left behind because bitcoin is more unreachable for their size because they consider bitcoin too expensive so it will be more worth it to start early while waiting and convincing that we are ready for a long investment relly maybe even up to 10 years ahead so that we get an optimal result from what we are doing now.
As long as we are still able to do it and as long as we understand what we are doing I think buying now will not be a problem because what we are waiting for is not a few months but years or even much longer.
At first you said to wait, and then now you said it is o.k. to buy now. I am not quite clear what you are emphasizing, even though it seems that now you are saying to buy.. I think that we need to know whether newbie or not.. .if brand new then buy, if you already have coins then you still might be a newbie and you should buy. I would also tend to suggest that if you have been buying less than a whole cycle, then continue to buy unless for some reason you had front loaded your investment along the way.
Another thing is that if we are buying every week, then why should we care if the price is high, low or somewhere in the middle? If we are a newbie, then how are we going to know if the price is high, low or not? Sure, we can see ATHs currently present, but does that tell us not to buy?
Maybe you know since you have presumptively been in bitcoin for two whole cycles (since mid-2016), and for you maybe you have already bought a lot or more than enough BTC over the years? Most folks have not had two full cycles to accumulate BTC, so if you are addressing your comment to any newbie then the question would more likely be whether they have any coins and if they have enough and if they don't then for them to keep buying.., yet they are still responsible for their own choices whether they end up buying or not buying.
