If you bought btc at a penny each and invested ONLY $100k you'd be sitting on 10 million btc right now.
When Bitcoin was a penny each there weren't 10 million of them. Do you think about what you're saying? It took 4 years for the first 10 million BTC to be mined. The 10 millionth Bitcoin was mined on Sep 22nd 2012 when the price was around $12 per BTC, and that's just the spot price. If you were trying to buy them all you would have pushed the price way higher.
Do you really think that the people who bought BTC cheap and held it all these years through the highs and lows were just "lucky"?
