.......to know more about bitcoin investment and how longer investment period guarantee more return than short term investment.
That still seems to be a misleading way of talking about anticipated BTC price performance, and even though there might be some technical truth that the probabilities of UP might be better the longer the time period, but even if the probabilities are higher, that still does not cause the long term to be guaranteed to be higher, even if the probabilities suggest that it should be.
There's gotta be better ways to present ideas about the advantages of long term investing versus short term thinking without devolving into ideas that the long term is more guaranteed to be better than the short term... even if technically what you are saying is not exactly incorrect, but the use of the term guaranteed comes off as misleading.
One thing about investing for the long term is that a relatively modest amount invested could end up adding up to a lot invested, so even though in the short-to-medium term, there might be some difficulties in measuring the amount of value that is retained, but there seems to be a bit of a likelihood for some kind of an upward price trajectory that could happen somewhere down the road.. or mayb even several upward price trajectories, so even someone who is investing relatively modestly, might be able to measure a lot of progress from the over the years modest contributions that end up outperforming other places that the value might have had been kept.. while at the same time, it is not guaranteed to actually go up in value.. but that is true with any investment that we choose to allocate into, we might have some investments that outperform other investments.
We hope in the end that we ended up picking a mixture of investments (hopefully not shitcoins) that put us into a better position than if we had not invested and/or saved.. but again, no guarantees and we attempt to do our best, even if there might be a large number of weeks that we are ONLY able to save/invest around $10 into bitcoin and then maybe there are other weeks that we are able to save/invest $100 or even $1k into bitcoin, so there may well be quite a bit of variance in our cashflow (and/or our disposable income) that affects how much we are able to save/invest, so that in the long run the variable amounts of value that we injected add up but they also may well have ended up holding their value pretty well as compared to other places that they could have been put and/or they might have ened up appreciating in value as compared with other places that the same value could have had been put.
