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

I would personally advise you to get around 50 just to be safe. Although, there is no way i see bitcoin being anywhere over 10,000$ anytime soon at all. If they go up to 3-5k$, well happy times for you!

50 is not enough actually, you need at least 100 BTC and in 20 years you can start saving now, regular saving is very important to accumulate a good number of bitcoin by 20 years and the amount or value will appreciate and that will be good for your investment, you will enjoy then.

even 100 bitcoins wouldnt be enough in my opinion you would need like a thousand or something like that

yeah agree of course it will not be enough. let alone in the future course of the year the cost of living would be very expensive. Of course you need more bitcoin for survival

Well based on the rate of inflation you can estimate how much it is going to cost every year from there on out, assuming that nothing changes much. the main thing that can be a huge issue unforeseen events such as quantitative easing and so which seriously devalue your currency and aren't always know to the public, aside from when they're about to happen.
