Obviously this depends on where you are located. Such as if you live in an expensive place in the US or Canada, then its a lot more than in other countries. Also if you are young, middle age or older.
I already have a calculation that only 2 bitcoins (at the current price rate) should make my life comfortable for the next 60 years. In my city, actually the price of basic necessities is not too high when compared to cities in Singapore or Las Vegas, so I'm quite grateful to be born in a country that doesn't make my life burden high lol.
