Lets assume I wanted to have $1.6million in bitcoin in 20years. If we ASSUME the growth in the price of bitcoin remains as is for the next 10 years, and not so much in the next(you can pick a %)
. How many bitcoin would I need to have today?
It's impossible to predict how bitcoin will grow. I believe bitcoin will grow on bubble-burst cycles with huge pumps, dumps and new floors.
Most people believe in 21 BTC being a good goal. Think in terms of total supply. 21 puts you in a limited group of 1 million (less, considering current supply + lost BTCs)
This should put you in a wealthy situation sooner or later. If you want $1.6mm.. then you'll need $71k per coin. It's probably realistic in 20 years.
That's too much by far. Bitcoin has only 2 ways. It will either keep growing and become accepted by most countries, possibly even as a secondary currency, an alternative in case the main financial system goes to hell, or die. If the former happens, even 1BTC will be worth a fortune!
Let's do some math. in 10 years almost all coins will be mined and at least 10% will be permanently lost or unusable (Satoshi's stash, lost keys and passwords) We'll be left with with maybe 18 something million in circulation. The population of Japan is 126 million, so there won't be enough coins to supply the Japanese, not to mention the rest of the world. When people realize that they'll buy out everything.
