You have to decide NOW how many bitcoins will make you rich in the future because it's getting to the point where an upper middle class American or European can no longer buy a full bitcoin.
Anyone have any ideas how many you'll need to be rich in 2020 and 2025?
buying bitcoin will never make you rich, working and earning money and using your time and that money wisely makes you rich. otherwise you can buy many bitcoins and hold them for years and with the price rise make a lot of profit but never be rich.
and besides an upper middle class American or European doesn't have to buy 1 full bitcoin today, he can gradually invest by buying small portions. like 0.1-0.25
BTC each month and moving it to cold storage for long term hodling.
