Sure it is good to have a longer time line, and that was part of the reason that I outlined the examples to show that the longer that we invest, even if we might start out at a market top, we still might well end up still putting ourselves into a good position.. even though surely it is not guaranteed, but we can see how our BTC portfolio is growing over a timeframe in which we might continue to buy for 4 years or more and then perhaps reassess if we might need to make any changes to what we are doing or just keep buying regularly.
The common problem with most investors is that they put too much attention on the short-term rather than the long-term.
Setting your gaze on the long-term and having a disciplined investment often helps to ride out market fluctuations because the fluctuations only affects the short-term investors.
Having a longer timeline also leads to a much stronger position in the long run.
Most investors believe there's a best time to buy, but fail to understand that everytime is considered a best time, because even if one buys at a market top and then HODL over a longer period of time, it can help to average out the cost as well as increasing one's chances of profitability.
Through regular BUYING and HODLing for 4 years or more, one can take advantage of the DCA strategy and reduce the impact of the short-term fluctuations. It's also very important to reassess ones strategy overtime as this usually helps to make necessary adjustments in one's approach and to make more informed decisions about one's investments.
Although, Investing in Bitcoin, just like every other investments is associated with lots of risk and do not guarantee success but at least, it'll be safer to know that a well thought out approach, patience, self discipline and persistence can help one to increase their chances of achieving one's long-term goals.
Even if an investor has the same strategy, he might end up buying bitcoin at a higher price and then a lower price, so even a guy that got into bitcoin earlier could end up having a higher cost per BTC than someone who came in later, but in the longer run, he still would end up having more BTC, so the time in the market may still end up being better, even if he ended up with a bit of a higher cost per BTC than someone who came in later. At the same time, there is ONLY so much value in comparing to other people, but a guy could still compare to himself at time one or time 2, and surely I am not much of a proponent for waiting, even though I know that sometimes, there may need to be adjustments to how much is bought based on anticipations of price conditions, including being able to buy BTC as the price is going down, if that might end up being a guy's point of entrance into BTC.
You're right that even with same strategy, people can still end up buying at different prices, leading to different costs per BTC purchased by each person. However the main point worth noting here is that, though timing the market isn't always the best approach but time in the market could actually still be a very notable factor in determining overall success.
Just as you've also pointed out, it's always better to focus and evaluate one's progress and make all the necessary adjustments in areas that's required, rather than comparing oneself to another person because it could actually turn out to be inexpedient and futile. Rather than comparing oneself to others, one could try making comparisons to their own previous positions as this could actually help to assess one's growth and also make all the necessary changes and adjustments for future growth.
