$100 a Week Into Bitcoin Since Its $126,000 Record High: What Would It Be Worth Now?
Bitcoin's historic hack sent prices tumbling nearly 40% from their peak, and one unlucky investor who started buying at the all-time high now faces a critical question: how long can dollar-cost averaging keep their portfolio from collapse?

A person who began investing $100 a week in Bitcoin (CRYPTO:BTC) from the date it hit its record high of $126,080 on October 6, 2025, has put in a total of $5,600. This investment is close to breaking even, with Bitcoin currently trading at $78,050—38% below the record high—and down 8% over the last 30 days. On October 30, Bitcoin closed at $77,223, marking its lowest close in a month.
The significant drop in Bitcoin’s price in late October largely stemmed from Binance halting trading after the largest hack in crypto history, which led to a $6.3 billion theft and sent shockwaves through the market.
To illustrate an unfortunate investor’s experience, 24/7 Wall St. tracked someone who started buying on the exact day of Bitcoin’s record high. The following numbers show the current value of their investment and what price Bitcoin needs to maintain for them to profit in 2027.
$100 a Week in Bitcoin From the Peak Is Close to Break-Even
The investor spent $100 every week, buying at the closing price on the day of each purchase from October 6, 2025, until October 30. This resulted in 56 total purchases, totaling $5,600 invested and 0.0719 BTC acquired.
At the close of October 31, when Bitcoin was valued at $77,474, the total worth of this investment was about $5,574, indicating a loss of just $26, or 0.5%. However, at $78,050, the same investment is worth about $5,615, a small gain of about $15.
The investor’s nearly break-even status stems from a strategy known as dollar-cost averaging. This method involves spending a fixed dollar amount regularly, regardless of the price. When the price drops, $100 buys more Bitcoin, lowering the average cost. In this case, their average cost ended up being $77,842, which aligns closely with Bitcoin’s current trading price.
| Start Date | Purchases | Total Invested | BTC Owned | Average Cost | Value at Oct. 31 Close | Gain/Loss |
|---|---|---|---|---|---|---|
| October 6, 2025 | 56 | $5,600 | 0.0719 | $77,842 | $5,574 | -0.5% |
| November 8, 2021 | 260 | $26,000 | 0.6062 | $42,890 | $46,965 | +81% |
Why a Buyer From the 2021 Peak Is Up 81%
For comparison, we also looked at an investor who began buying near Bitcoin’s 2021 peak on November 8, 2021. After making 260 weekly purchases and investing $26,000, this buyer now holds 0.6062 BTC worth $46,965, resulting in a gain of $20,965.
While this investor also started at a peak price, they continued to purchase through the bear market of 2022, which saw prices decline significantly. As a result, their average cost of $42,890 is much lower than Bitcoin’s current trading price. The 2025 investor, however, hasn’t experienced a profound price decline yet, so their average cost is closer to the current market value.
Time has greatly benefited the 2021 buyer. Bitcoin has risen about 124% over the past three years, and its market cap is now approximately $1.57 trillion, with about 20.1 million out of a maximum of 21 million coins already in circulation.
ETF Outflows Put Pressure on Bitcoin’s $77,842 Break-Even Price
When examining market trends through Spot Bitcoin ETFs, which are funds that hold Bitcoin directly and trade like stocks, we can see the behavior of larger investors. On October 30, these funds recorded $643 million in net outflows, the worst day of the month, after a $528 million inflow on October 21, the best day. Since the launch of these ETFs, cumulative net inflows have decreased to $57 billion from $58 billion as of October 21, and total assets have shrunk to $98 billion from $111 billion on October 5.
The recent hack disrupted Bitcoin’s short-term price trend. A moving average is calculated by averaging the closing prices over a specific number of days, allowing traders to assess price direction. Currently, Bitcoin trades below its 20-day moving average of $81,023 and its 50-day average of $81,906, but remains above its 200-day average of $73,136, indicating the long-term trend is still intact.
Meanwhile, M2, which measures the broad money supply including cash, checking and savings deposits, and money market funds, continues to grow. As of September, it reached $23.4 trillion, an increase of 0.5% in just one month, the highest level since at least November 2025. This increase in available money often flows into assets like Bitcoin.
Can $100 a Week in Bitcoin From the Peak Stay Profitable Into 2027?
An investor who started buying at the record high has a solid chance of staying break-even or even in profit by 2027. Bitcoin simply needs to remain above $77,842, which it is currently doing. Every new $100 purchase helps adjust the average cost, and if prices drop, that average cost will decrease even further.
For Bitcoin to hold its ground, it must maintain its October 30 close of $77,223 and recover its 50-day moving average of $81,906. Additionally, ETF inflows need to return to a stable positive trend for prices to stabilize.
However, if the aftermath of the hack worsens, the next significant support level could be at the 200-day average of $73,136. Bitcoin’s low close of $58,566 on June 30 highlights the volatility it has faced over the past year. A daily close below $73,136 would deepen losses for the current investor. Still, the 2021 buyer’s 81% gain suggests those cheaper purchases could pay off if prices improve over the coming years.
