If you'd spent just $2 on the right numbers for the 1/13/16 PB drawing it would have been worth about $130 to $150 million just a few days later.
Of course you didn't pick the right PB numbers, and you didn't buy $1000 worth of Bitcoin in 2010. Considering that there were only about 4 million bitcoins in existence at that time, a value of 5 cents each meant that there was only $200,000 worth of bitcoin available to buy, so it would have been impossible for more than about 200 people to have bought $1000 worth back in 7/10.
History is chock full of things that offered incredible opportunities, but only the people who could see the future knew for sure how good those opportunities were. With some of those opportunities some people were correctly confident that they were good or great opportunities. Most people were just ignorant, though some of them got lucky.
History is also full of things that turned out to be lousy opportunities. Your ancestors could have tried to come her on the Titanic or the Hindenburg. And as I alluded in my previous post, you could have jumped on the dot.com bandwagon and bought $1000 worth of pets.com stock. If you'd sold it at its peak you would have made a profit of about $272 (before paying income tax at short-term capital gains rates). More likely you'd have tried to sell it while it was dropping like a rock, or still stuck with it when it was worth a whopping 1.7% of what you'd paid for it.
Nobody can be positive about what the future value of Bitcoin will be, but there is one thing I can be positive about. What you could have made if you'd bought it 7 years ago is a really poor reason for buying it now. As every ad for an investment says, past performance doesn't guarantee future returns.
