How many bitcoins do I need to retire in 20 years?

[Amph]

If the bitcoin price reaches $1million in 20 years, you just need two bitcoin. It depends on the adoption of the bitcoin in general.

I think its impossible in 20 years maybe price will be around $2000-$7000
that's obvious you need a lot of bitcoin before retirement

another idiot.

If bitcoin doesn't go up significantly, people will give up and sell their bitcoins, crashing the price.

No. It can't go up significantly.

If it goes up significantly, the demand will be met by an alt-coin.

the nature of the controlled supply will force a value increase, in 10 years, where the miners will need at least 5k to survive, if the hashrate and the diff will keep increase like now

the same margin of profit will be maintained, all this without counting the possible higher demand...

$1 million is very high in 20 years, but who knows..lets just hope that bitcoin would live that long, and yes, adoption would make bitcoins last long,,
you will be having a very good life if you have that amount of money.. 

We only need the bitcoin price to rise 47% a year for it to reach $1,000,000 in 20 years time.

No dude, you can't say that 47% of 1,000,000$ means only 470000$ this much money enough for after retirement. It is totally dependent on the how are theirs movement, expensive place or cheap place and how will you expense your money according to you.

If the price rises 47% each year, it will be 2500 times of present value, so $400 will be $1 million.

who will buy bitcoin if price at $1million, i don't think bitcoin can reach that price even though in 20 years again. i think the highest bitcoin price is around $1000 - $2000

[babs1975]

I would advice you to buy as much as you can, most probably 100 bitcoins. By the time you retire in 20 yours, the price would have increased 1000th fold and you will be able to live a comfortable life.

The US state debt is $19 trillion. If people lose confidence in US dollar and the US government has to borrow bitcoin to fund its operation, the bitcoin price will be at least $1 million each.

lol borrow bitcoin to fund its operation... you wish.

Bitcoin can reach $1 million each, and that still won't happen.

But the question "who will buy bitcoin if price [is] at $1million" is something only an idiot would ask.

I for one would not mind buying fractions of a bitcoin, if the market price was $1 million each. And any logical person would. It's basically the exact same question as "who would by 1 million 1-dollar bills for $1million?"

I think 100 bitcoin is enough But no one knows bitcoin in the future,  you can make your own prediction and make your purchase.

100 bitcoin at the current price? That's like a year's salary. But then again, it depends where you're retiring.

Its big, In where I live, it would take more than five years to accumulate that big amount, lucky are those early birds who collected the first bitcoins.. 
Anyway, I think 100 is good enough for me...

[bitcoin-hunter]

I think Bitcoin itself is safe. The only thing that is less secure, I think the online wallets.
I had heard that you can be hacked there.

[praprata]

I think you still need a lot of bitcoins to by rich forever and stay rich forever.
I think you can be rich in 20 years with about 60 btc.

60 Bitcoin is a lot of money in 20 years. The price will be at least $200,000 each in 20 years. So 10 is enough.

[mnightwaffle]

guess w/o any info

btc will be > than 30k a coin, before 2030
 
Which is stupid....

but hey.

  nice value. I hope that will happen. 1 will be enough for me if it is really in that kind of price. I have many things I can buy with that large kind of money. So my 1 bitcoin should stay.

[phreaky]

I think you need a lot of bitcoins to retire in 20 years with bitcoin.
The question is if the bitcoin than still exists after 20 years, will it survive ?

I'll probably trade it for ETH after a year or two. If the bitcoin strength decreases due to the upcoming altcoins, we need to adjust as well.

I think 100 bitcoin very little to the cost of your retirement in the 20 years to come you can collect more than 100 BTC within 20 years. it will help you later in the future

[MaxTax]

I think you really need a lot of bitcoins.
Namely because you intend to buy anything, etc.
But I think it can not because imagine Bitcoin will no longer exist.
