This part is true... A person needs to be invested into bitcoin in order to profit from its likely future appreciation, and even though it is not guaranteed that bitcoin will go up in value, it still seems to be a pretty good bet that it is more likely to go up rather than down, especially if our plan is to hold it for at least 4-10 years or more. Another thing is that there are other possible places to hold the value, and surely cash is more likely to continue to be debased and to therefore go down in purchasing power, yet at the same time, some folks might be lured into various other places to invest besides bitcoin, so it may well be a worthy cause to study bitcoin while investing into it in order to hopefully gain confidence about bitcoin being amongst the best of places (if not the best?) to put value, even though it is not guaranteed that it will go up in value... it is still a good asymmetric bet which means that if you do not employ leverage, then the most that you could lose is 100%, but there is also great upside potential, too.
I thought about it, I used to deposit a specific amount in the bank as Fixed DPS before and the funny thing is that after a few years, the inflation has been much higher than the profit I am getting from that bank DPS.
For example, what I could buy for 5 dollars then, now it is not possible even for 10 dollars.
On the other hand, if we compare the price of Bitcoin, then in a certain cycle of time it gets a bear season and the price decreases by more than 70% but the interesting thing is that every time its price decreases in the bear season, the minimum is much higher than the bear all time low price of each season.
And besides, if we talk about the bull season, then in this case the fund brings several times more profit. Which we cannot even imagine as an interest from the bank.
So in my opinion, instead of making a fixed deposit in our bank, we invest in Bitcoin with a fixed deposit strategy for the long term, which will not inflate our assets.
And besides, if someone can hold Bitcoin for the long term, at least 8 years, I believe they will definitely be profitable. The logic is here so simple, after the 8years the earth population won't gonna same and as well these 21millions will have more adopter and as well that will increase the demand and demand will increase the price automatically

Well, even if you had made some mistakes in your 8 years on the forum, and if you had not accumulated enough BTC in the past 8 years, you are still advantaged to be getting started and getting more serious about accumulating bitcoin... so yeah, your dollars and your fiat or going to be losing value way faster than you can stack it and it becomes quite difficult to earn any returns on the dollars that you save, and even if you can figure out some places to put your dollars to try to earn some returns...
And yeah bitcoin is volatile and it is not guaranteed to go up, yet it seems that at the same time it is amongst the best of places (if not the best of places) to be putting value for a large number of people around the world in terms of whatever that they are able to save up for a couple of cycles or longer.. then it is likely that their purchasing power is going to be better preserved by keeping the value in bitcoin as compared with any other place that it can be kept.
Another thing is that if the value kept in bitcoin builds up, then there is also some importance in trying to make sure that the value is safe and that third parties are not able to interfere with it... so there are likely benefits in for normies to learn how to maintain their private keys and to safeguard such keys with back ups, too.
