I've got the chance to have at least 10 bitcoins in the past but the ignorant and idiot me made me sold a lot during the early days. Well, like everyone's story of selling too early because of FOMOing because we thought that it would crash to death but they're all noise. At least owning 1-5 Bitcoins would make you a millionaire maybe after few more years and that's enough for retirement given that you have some other source of income that generates passive or active money with lesser efforts.

The more the better because it will grow much greater value for the growth of the assets we have, but the question is how big is the opportunity to accumulate if someone does not have a good strategy without adequate capital support.
I think it can be done if someone understands how and we can see the extent of someone's role in getting the right accumulation method with the financial constraints they have.
In some capacity we may be able to make a plan to prepare a much better amount of bitcoin for retirement and it depends on our level of consistency in achieving it.

If we have the intention then I am sure it will be easy to get even using the DCA method in the accumulation process and most importantly done consistently even by buying in smaller amounts.

Bitcoin was very cheap at earlier stages, lots of people sold at lose cause they were very ignorant of the future, they never thought the new innovation would be a life changing opportunity in years to come else i believe they would've taken it very seriously, anyways i don't realky blame them cause someone bought 1pizza with thousands of Bitcoin back then so i  believe ignorant played a role too.

 Anyways i like that you're not very greedy i feel so cause 1-5 Bitcoins if held for a longer period would turn into something more profible, well a lot of people in my county would sell immediately they're given such amount, it's a life changing opportunity and the present economic Situations would make anyone to sell, on the other hand it would be more better to sale some portions if not everything.

We dont know on what the future brings on which in regarding on the question on how many Bitcoins would really be that enough? There's no such thing about enough because we will really be that targeting or would really be that liking to have as much as possible because human beings are naturally greedy on which simply means that the more coins that we do have then the more better. When it comes to price there's no way that it could be known but to assume out about its potential then 10-20-30 years from now will really be having that positive outcome or results when it comes to value on if we do possess out tons of coins then there's no way that we would be problematic about financial aspects.

For me then i would say that 100 Bitcoin will really be that enough or i can say that even into this current price then it should be sufficient but just like on what i have said above that there's no such thing about enough coins because as much as possible on the moment that we've seen up on what we can be able to grab then we will be that doing it as much as possible. We are that aiming for having that assurance that we can live without having any problems.

If you think the bigger is the better, I'm sure you will never retire because you keep thinking to make money.

But, that's fine because there are people who workaholic, they choose to work instead of retiring even they have money. I think 100 Bitcoin are enough for any people in this world, 10 Bitcoin is too small for developed countries, it's just $1 Million while housing price are around $300K-$400K, that's already consume 3-4 Bitcoins, not to mention about car and other thing.

This is a matter of relativity!

If you are retiring now at retirement age with Bitcoin priced at average $100k you would probably
need . . . IDK 3 Bitcoin which would probable last you between 6 and 8 years.

But here is the kicker, its really difficult to answer the OP's question because it only throws up more
quesitions

What are are you retiring at?

What sort of lifestyle do you plan on living, will you need $50k per year or more?

How do you view the Bitcoin market in the future?

Also we need to remember - when we decide to retire we are not going to liquidate our wallets on
day 1 of retirement, we live day to day, week to week as it is and this isnt going to change because
we decide to retire.

I don't know how many bitcoin would be enough for me to reach that fuck you status, whereby I don't need to work for anyone since my bitcoin hodlings is enough to take care of whatever I want till death. I feel 10btc will be enough but very difficult to accumulate overtime with DCA, because bitcoin price keeps on increasing overtime. However, I wouldn't love to depend on my bitcoin investment alone after retirement because I will set up other means of income.

The bigger the community that is built, the better the journey of bitcoin will be even though in the end the price will not be as volatile as it is now, but in terms of growth this will make bitcoin one of the best that has ever existed.
Nothing is impossible because it concerns ownership, it can continue to be accumulated according to the capital we have and the advantages of investing in bitcoin can actually be run according to the capital we have without having to force it excessively.

There are many methods that can be adjusted for accumulation patterns and it depends on how we try to run it, thus we will continue to get the opportunity to collect it in a much more appropriate way.

Since Bitcoin is volatile, of course the best course of action is to buy more when it dips.

And keep buying a certain amount independent of the price, because maybe it will never get below a certain price.

It's like saving in the end. It's an asset that appreciates over time.
