What you´re saying ? I´m a rich bitch, or, . . . naah
I'd start with $100k, which is maybe this year or next year, we don't know for sure. $1m will come in a few short years, so keep a few set aside in cold storage or something. You can go play (and probably lose) the rest.
In my mind, between 2025 and 2035 is when all the "practical" bitcoins have been mined, or we are close to 99% mined. The next one hundred years is for the last bitcoin, and that quantity matters less, but cost of production of those last few bitcoins will drive the price of the entire marketcap.
Here is the coin supply schedule estimated:
Current bitcoins: 16 million, Block Reward 12.5 BTC
By 2018: 17 million
By 2020: 18 million, Block Reward 6.25 BTC
By 2022: 19 million
By 2024: 19.68 million 93.75%, Block Reward 3.125 BTC
By 2028: 20.34 million 96.87%, Block Reward 1.5625 BTC
By 2032: 20.67 million 98.44%, Block Reward is below 1 BTC.
By 2036: 20.83 million 99.22%
By 2056: 20.99 million 99.99%
By 2064: Less than 1300 BTC added per year
By 2080: Less than 100 BTC added per year
By 2100: Less than 2 BTC added per year
By 2108: The last full bitcoin has been added
By 2144: Mining is purely transaction fees.
Between 2036 to 2144, most or all miners will receive more in transaction fees, than the coinbase block reward.
I think 2025 to 2026 which is less than 10 years away, for all intents and purposes, all bitcoin has been practically mined, and we should see price adjust accordingly. USD is likely to be 100k to 500k by this time, depending on who you believe predicts the price.
2030ish is the decade where we see bitcoin go full million dollars or higher.
