Teaching from a young age how to invest in bitcoin will help our children understand what we are doing.
Bitcoin is a good investment in the future and if we buy it now 5 or 10 years from now the price may be much higher than now.

Bitcoin can also be an inherited asset that we will give to our children later. It is the perfect long-term investment.
It is not regulated by governments or third parties, only users can regulate it. there are no storage fees or other charges. 

There is one point the OP mentioned which is _almost exclusive to Bitcoin and really
counts on its decentralised nature and that is the transfer of it from one person to
another without the receiver having to incur taxes.


In my country inheritance over €16,000 can be taxed at 33%, the transfer or inheritance
of Bitcoin sidesteps this tax.

One of the obstacles you will receive from your thinking is the market. you know the market for Bitcoin has a very volatile value. if you have a good old days plan but when you want to cash out your Bitcoins in fiat to fulfill your plan but not according to market conditions. then you are at the wrong time. That's because no one really knows the fate of your long-term investment. although I'm sure Bitcoin will be great for the future, but every moment sometimes forces us to sell Bitcoin at prices we don't plan.

I don't need to advice you to always have at least some Fiat stores in your bank, having some Fiat in your bank won't stop you from holing your Bitcoin for a long period of time but it's because of emergencies that's why it's not a good plan to put all your money in Bitcoin, there will always be volatility moment in the future of Bitcoin, so to tale profits sometimes will feel wrong because you will be selling your coins for more sats at lesser value, if you understand what I mean.

I also want to be a long term Bitcoin holder and possibly plan my retirement with crypto but we can't push Fiat away as if it's not useful at all, remember that to get what we all desire for we still need Fiat because not all businesses accept Bitcoin or any crypto.

I agree with your idea, I am building myself my retirement savings plan in BTC month after month and I believe deeply in the potential of BTC in the very long term.

I agree with almost all of the points you made, but we shouldn't focus solely on the positive aspects of BTC for a retirement plan.
It is true that no one will know about a potential inheritance, it is true that the documents and paperwork required to justify a pension are exhausting. But BTC also has potential disadvantages for a pension plan, such as:

- in some countries it may be extremely taxed, and if you can't pay things directly in BTC, the taxes can be painful
- PoW coins could be banned because of stupid pro-environmental ecological laws (like what is coming with the MiCA law in the EU)
- even if I am confident about the very long term, the value of BTC fluctuates and this could cause problems and unforeseen events at unpredictable moments

But as said, I am globally as convinced as you are of the advantages of Bitcoin for the construction of a savings plan for my old age, I just think that it is necessary to remain objective on the qualities and drawbacks of such a plan

It will only be great and beneficial if Bitcoin keeps on up-trending.  What if in the middle of the waiting process, Bitcoin suddenly collapses?  Would you still consider it beneficial?  There is always a risk in the process.  It is good to look at Bitcoin in an optimistic way but we should never set-asides risks and possibilities that can happen in the future.  We should always think about the other side of the coin.  Weigh them and come out with a more balanced approach that will not jeopardize our retirement fund.

I think it is always best to balance things.  While we are into Bitcoin investment, we should also diversify and not put all our eggs in one basket.  

The rest of list shows the convenience of Bitcoin over fiat services since it’s decentralized and you full control to your finance.

This benefits can only go wrong in to disaster if ever the price of Bitcoin collapse by the time you want to retired. Sometimes timing and destiny is too cruel on us. It will hit as a bad timing such as market crash on times that we need it the most. Bitcoin retirement benefits is like a double edge sword. It can give you 3 way result.

*More money than you save
*Same amount of your savings
*Less amount than what you save

There’s always a time that Bitcoin erased the previous profit in a cycle. Still this is a good plan judging by the overalls chart of Bitcoin which is continuously increasing for more than a decade. Finger crossed that this huge parabolic curve will not gonna end badly.

Maybe many people will agree with bitcoin as a retirement fund that they have invested in since they were young because of course it has benefits that are easier to control themselves than relying on government pension funds, of course there are some requirements that are too complicated and that's what many hate because it won't be that easy.

Bitcoin won't be in the bag forever with prices continuing to rise, but think about how bitcoin crashes because it has high volatility so we can't prevent it, not to mention that it causes other factors that affect the value of bitcoin to fall, so if you only rely on bitcoin then it's not will be able to except having a lot of bitcoin in the wallet maybe we will cover all the needs of his old days.

Keep diversifying while you can take advantage of bitcoin from now on and buy some properties that you think the price will go up, the rest you can use bitcoin as a reserve asset or both funds.

How many have already decided to make Bitcoin as their retirement plan? Answer: too many. All of those factors you've said are good and someone can easily sell Bitcoin at anytime an individual wishes to do it. There's no intervention from any third party and the retiree can get his money anytime that he can no matter what is the situation of the market. While many can't take a whole bitcoin as a savings, don't think about that but make sure you're able to save as much as you can and that's the plan for your retirement money. We may not be as wealthy as the others but we're wiser than them who doesn't think this way. A smart person will still have his benefit at the end as we grow older and we'll enjoy it through our retirement.

You are absolutely correct in the way you think about Bitcoin.  After retirement, there is usually a lot of harassment to get the retirement money in your account. You have to apply at different places for this one-time amount. And when that money is found in hand after a lot of harassment, it is seen that there are many arguments about that money, many family members are demanding a share of that money and the person has to face various other problems. If the person has Bitcoin investments then the person retiring will not have to suffer all these harassments. So everyone should invest in Bitcoin regardless of age.
