Your Bitcoin Investment
In January 2015, $500 at $250 per coin would have purchased exactly 2 BTC — two whole Bitcoin, a milestone that fewer and fewer investors will be able to claim as price increases.
At today's price of $70,000, those 2 BTC would be worth $140,000. A modest investment during a period of peak pessimism transformed into a significant financial asset.
What Happened Since 2015
The 2015-2025 decade was Bitcoin's transition from a fringe technology experiment to a globally recognized financial asset.
The growth trajectory: - 2015: Bear market bottom at ~$150, slow recovery through $400 - 2016: Steady accumulation year, second halving in July - 2017: Explosive rally from $1,000 to $19,700 on retail mania - 2018-2019: 84% drawdown and slow recovery - 2020-2021: Institutional adoption drives Bitcoin to $69,000 - 2022: Crypto winter — FTX collapse, Luna crash, BTC falls to $15,500 - 2023-2024: ETF approval, fourth halving, recovery past $70,000
Through all of this, your 2 BTC remained 2 BTC. Bitcoin's fixed supply means your percentage of the total 21 million coins never changes — the only question is what the market values that share at.
Key Events
The power of buying in bear markets: January 2015 felt like the worst possible time to invest. Bitcoin had just lost 87% of its value. The largest exchange had collapsed. Mainstream adoption seemed impossible.
Yet this is precisely when cycle indicators showed maximum undervaluation. The 2-Year MA Multiplier placed price deep in the green "buy zone." The MVRV Z-Score was negative. The Mayer Multiple was below 0.6.
History rewards those who buy fear and sell greed. The investors who had the conviction to buy 2 BTC at $250 — when the media said Bitcoin was dead — were rewarded with a 280x return over the following decade.
DCA Comparison
What if instead of investing $500 at once, you had DCA'd $500 per year ($41.67/month) starting in January 2015?
By spreading purchases across 2015-2016, you would have accumulated Bitcoin at prices ranging from $150 to $700. Your average cost would have been lower than the January 2015 price in many months, boosted by the sub-$250 prices available through much of 2015.
Both strategies worked. Whether lump sum or DCA, 2015 was a generational buying opportunity. The key was participating at all — most people didn't, because the fear was overwhelming.
