Early Bitcoin Mining Genesis
Download Bitcoin Core, leave PC running to mine 10,000+ BTC, backup wallet.dat on multiple USBs.
Preparation
In early 2009, prepare a few standard desktop computers or laptops. Download the early Bitcoin client (e.g., Bitcoin-Qt) directly from the links shared by Satoshi Nakamoto.
Execution Steps
After installing the client, simply enable the "Generate Coins" option. The network hash rate was virtually non-existent, meaning your CPU would easily solve blocks. You could mine dozens of blocks per day, each rewarding 50 BTC. Aim to accumulate 10,000 to 100,000 BTC. Alternatively, in 2010, buy them for fractions of a cent on early forums.
Exit Strategy
The ultimate challenge is secure storage. You must back up the wallet.dat file on multiple USB drives, CDs, and print out private keys to store in a bank vault.
Sell in tranches during the bull runs of 2013 ($1k), 2017 ($20k), or 2021 ($69k) to achieve supreme financial freedom.
