However, I come to think that those that want the price of Bitcoin to be reduced are the ones that are so scared and greedy. At the same time, they don't want to buy at a high price, so they are waiting for the price to reduce. (I am trying to say, people should not mix fear and greed when investing).
Just buying regularly will have good chances to get the investor into a better mindset, and if they are worried that the BTC price is too much, then just buy less, but probably not so great to stop buying unless you have reached some kind of BTC accumulation goal that justifies making such downward adjustments to regular and ongoing BTC buys.
If one constantly buys without fear or greed, I seriously think that the chance of achieving
half BTC or full BTC with $200 weekly in 10 years will be so near that the scared mindset can't be compared with at it.
Those that can not buy now are losing, but they don't know. Why I say what I said is because, with only the capital in their hands or in their pockets, they are not making any profit from it and some of them end up using their money for something that's not even important at all. So you said, I agree with that, buying regular is the most important thing to do.
Let me add to these ideas a little bit.
1) I am pretty sure that buying a continued $100 per week for the next 10 years will either directly result in 1/2 of a bitcoin (that would be $52k invested into bitcoin), and/or the person who is consistently investing that amount on a regular basis is going to be likely to also increase the amount from time to time, even if the aim might be to buy $100 per week, the average is likely going to end up being higher than $100 per week merely based on the setting of such goal and following through with it.
You are absolutely right, but as days pass by, one can get more money than he or she normally gets before (just like a promotion at his or her workplace or something else that he or she does for a living).
So, if a low salary earner constantly buys BTC that is worth $100 every week and then he or she finally gets promoted at his or her job or even gets a new job that pays him or her so well, then the person can consider increasing the amount of money he or she put into Bitcoin weekly.
Therefore doubling the amount to $200 per week (which would end up being $104k over 10 years) is likely to reach a whole bitcoin... but like you suggested, there remains a certain level of uncertainty, but it seems to me that if someone really has a strong goal and is attempting to take actions to follow it every week, then in those kinds of situations goals tend to guide towards exceeding the goals. That has been my experience. Another problem area is the health of someone, so if emergencies happen and a person who could previously work with his brain and/or his body comes into poor health, then sometimes they have to abandon their goals and to become more realistic which maybe results in a lower amount invested into bitcoin.
Honestly speaking, I haven't thought about this before. But this is true. Low health is one of the problems one consider first.
If someone has been trying his or her best to meet his or her plans to achieve something that will help them but suddenly he or she becomes mentally exhausted or ill, then I think health comes first. Without good health, one can not make up or achieve anything, and it might still cost the person to spend more or touch the savings he or she doesn't want to.
Most time one can decide to reduce the amount of money he or she put into an investment just because he or she wants to regain himself, but honestly speaking, I believe that if the same investor gets better, he or she can afford to continue the same way or above what he or she was putting into the investment (Bitcoin).
2) "Those that can not buy now are losing." Action is a pretty big component that helps to inform further action and also has more potential to facilitate learning rather than not taking actions.... so even if someone is really scared to take action in regards, to bitcoin, such person could start to study bitcoin for 1-2 months and then set up an account and be buying bitcoin a few months from now, and yeah, that would be slow action, but it is better than no action... just like getting into bitcoin now is better than the person coming into bitcoin into the future, just like it is better if you had already gotten into bitcoin in the past.. so time in the market is an important contributor in regards to both making progress and expressing commitment to the cause of accumulating bitcoin.
There is no need to contemplate whether to buy now or not because, as there is no robot or personal AI that can detect when Bitcoin will dip or skyrocket, the investors speculate about the price, then I don't think we should not but when we have the money to.
Most people, because of the way the price of Bitcoin might be high, will not buy because they are scared that Bitcoin will drop any moment. However, I don't depend on the dip because, if I do, I will definitely not buy it at all.
I believe that in investments, actions speak louder than the voice, because one might be saying that he will buy, he will buy, but maybe the letter ends up not buying like a single Satoshi at all, but most times, those that don't talk about investment quietly invest and accumulate without fear or greed.
