Bitcoin as we see it now will become more and more scarce as time goes on, so you wouldn't be wrong in your thoughts about it becoming even more valuable.

HOdling through is the way to go 

Inheritance is a good way to go, imo. Especially if everybody will appreciate you hodling for that long 

Many people disregard such activities, but your family will surely appreciate your hard work which you did thoroughly and steadily.

I think it really difficult to say what the preferred investment will be because the dynamics would be an entire different scenarios by then. The pizza meant something then right?? as regards to value while the tesla we think is something now might no even be regarded 20 years from now  as it is regarded this day.
New technology and things to invest in must have taken place So the best hope is it improves and sustainable over a long period of time in order to maintain the asset.

The total is 20 Btc and that is a very large amount compared to the current price of Bitcoin, and I think almost all old users must have more than 5 Btc Bitcoin if they total it up until now. And even though we currently only have a little or even no Bitcoin at all, what is important is that Bitcoin has made us better financially or has realized something very valuable to us even more than that and that is an amazing thing because I also feel it and things like that are something that may not be available out there other than Bitcoin and we are lucky to be involved longer.

And there must be regret because we would not have thought that the price of Bitcoin could reach an extraordinary price like now and maybe it will continue to increase, so we can start again and continue to collect more Bitcoin to be able to realize what we want for many people in the future such as family or others, because that is a noble deed and intention and I am sure we can definitely make it happen because we believe in the long term Bitcoin can realize anything we want and I pray that your plan to build a school can be achieved and also get more Bitcoin.

And I also think the same, in the next 20 years Bitcoin will most likely be used as a legal tender by several countries and can also make many people's wishes come true, especially helping their finances.

I don’t have anything specific as of now of me replying to this post, but that will tell what one will want at that time by holding bitcoin for that long. You may wish for something now in several years later when your bitcoin is matured enough to be spent, you’ll wish for more and that’s how it goes on. For now, let it be as an investable asset that can be dependent as a profit driven asset until and when the time to use it reaches. You can wish for all you want now but if you’re not taking action to buy them now, you’ll wish for something lesser of higher depending on the price at that time relative to what you want to purchase with such amount of money Bitcoin will be worth in your portfolio by that time.

What I will buy with bitcoin in the next 20 years to come will be determined by its price and the cost of living as of that time. I don't know the worth of properties, considering how all countries currencies are devaluing.

Inflation is at the doorstep of everything; if inflation doesn't sink us down to the ground where $100,000 won't be able to purchase a bicycle, then I will be able to make a good decision about what I will hold by that time. For now I can't decide because we are talking about a future filled with uncertainty.

As at the time of the pizza incident,  Bitcoin was way lower than $2 and so it was one of the reasons it may have probably been Priced for pizza by the guy who did carried out the transaction back then. Sighting that as a case study and wanting to invest in Bitcoin now with a 20 years projection in mind, by the end of the 20 year tenure I believe Bitcoin will be way worth more then the items you have already mentioned because because 20 years is far too longer than 15 years and it took 15years to worth such which means it took it 15 years to get over a thousand times more than it was priced then and so now in twenty years it's obviously going to do way even more and worth more valuable goods of which if I have a  bitcoin by then, I will be buying a real estate with it most definitely.

The future of Bitcoin in 20 years is not certain to us. I am planning to meet all my financial needs and wants through my long term plan of Bitcoin investments.

20 years is a long year from now. Based on halving calculations, till then, about 5 halving will make up that time. I can't imagine how the crypto market will be by then and what price Bitcoin would have been by then. It could reach $2 million or above, or less the price. I am optimistic that many countries will legalize Bitcoin by then. What we are exchanging our Bitcoin for, currently, will be of big money by then.

To be honest, we do not know what the future holds for us. I'm personally clueless about what I'm going to do with my Bitcoin in the near or distant future; I don't even know how I am going to withdraw them, as I'm fearing a potential taxation on my funds. It's still too early to make up my mind; although I've managed to acquire a reasonable amount, I haven't thought about it at all; I just blindly accumulate as much as possible.

I understand that this isn't the wisest approach; I believe we should always plan ahead or at least have a basic strategy in place, but right now I can't come up with anything that's so ahead of us. On top of that, we can't simply hold forever; at some point, we'll have to sell. Perhaps me not being in an actual need for my funds led me to not set up a plan on how to manage my Bitcoin.
