Figure: Bitcoin’s historical price (USD) over 2013–2018, sourced from CoinMarketCap , showing a surge to nearly $20K by late 2017. Under our hypothetical model, continuing exponential growth from $108K in 2025 would yield an even steeper curve, shooting toward ~$21M by 2046. (The projected curve is conceptual; see table below for exact values.)
Building on Saylor’s forecast (a ~29% annual rate to hit $21M in 21 years ), we apply the compound-growth formula A = P(1+r)^t with P=\$108{,}000, r=0.285, and t years from 2025. This produces the year-by-year prices and cumulative returns shown below (returns are (\text{Price}t/\text{Price}{2025}-1)\times100\%) .

| 2025 | 108,000 | 0% |
| 2026 | 138,780 | 28.5% |
| 2027 | 178,332 | 65.1% |
| 2028 | 229,157 | 112.2% |
| 2029 | 294,467 | 172.7% |
| 2030 | 378,390 | 250.4% |
| 2031 | 486,231 | 350.2% |
| 2032 | 624,807 | 478.5% |
| 2033 | 802,877 | 643.4% |
| 2034 | 1,031,696 | 855.3% |
| 2035 | 1,325,730 | 1,127.5% |

| 2043 | 9,855,532 | 9,025.5% |
| 2044 | 12,664,358 | 11,626.3% |

| 2046 | 20,911,705 | 19,262.7% |
Each year’s price is rounded to the nearest dollar. The table shows a hyper-exponential rise: by 2035 the price exceeds $1.3M (over 1,100% gain), and by 2046 it hits ~$20.9M – roughly a 19,263% total return versus 2025. Cumulative return is computed as (\text{Price}_\text{year}/108000 – 1)\times100\% .
Plotting these values yields a sharply upward-curving line. In other words, under a steady 28.5% CAGR the price path would be very steep (convex upward), dwarfing the historical trend. This illustrates the scale and excitement of the projection: an investment would grow from $108K to ~$21M in two decades, matching Saylor’s dramatic forecast .
Sources: Constant‐growth math (compound formula ) and cumulative-return definition underlie the calculations. The $21M/2046 target and ~29% rate reference Michael Saylor’s statements . (The historical chart is for context ; the forecast uses the stated 28.5% rate.)
