What is Sats per Dollar?
Sats per dollar tells you exactly how many satoshis (the smallest unit of Bitcoin) you can buy with one US dollar at any given moment. It's the inverse of the Bitcoin price - as BTC gets more expensive, each dollar buys fewer sats.
This metric is popular among Bitcoiners who prefer to think in sats rather than fractions of Bitcoin. Instead of saying "I bought 0.00095 BTC," you can say "I stacked 950 sats per dollar invested."
How to Calculate Sats per Dollar
The formula is simple:
Sats per Dollar = 100,000,000 / BTC Price in USDFor example:
- At $100,000 per BTC: $1 = 1,000 sats
- At $50,000 per BTC: $1 = 2,000 sats
- At $10,000 per BTC: $1 = 10,000 sats
- At $1,000 per BTC: $1 = 100,000 sats
The lower the Bitcoin price, the more sats you get per dollar. That's why Bitcoiners often say "stack sats while they're cheap."
What is Stacking Sats?
"Stacking sats" is Bitcoin slang for accumulating satoshis over time. The idea is simple: regularly buy small amounts of Bitcoin (measured in sats) regardless of the current price. This is also known as dollar-cost averaging (DCA).
The "stacking" metaphor emphasizes that every satoshi counts. Even if you can only afford to buy a few hundred sats at a time, they add up over months and years. With Bitcoin's fixed supply of 21 million coins (or 2.1 quadrillion sats), each sat you stack represents an increasingly scarce piece of the network.
Historical Perspective
Looking at sats per dollar over time tells the story of Bitcoin's appreciation:
- 2010: $1 could buy over 10 million sats. Bitcoin was essentially free.
- 2013: $1 bought about 100,000 sats when BTC hit $100.
- 2017: The bull run brought $1 = ~5,000 sats at $2,000/BTC.
- 2021: At Bitcoin's then-ATH of $69,000, $1 bought only ~1,450 sats.
- 2024: With BTC at $100,000, $1 = 1,000 sats.
The long-term trend is clear: each dollar buys fewer sats over time. This is why many Bitcoiners view accumulating sats as a race against time.
Frequently Asked Questions
What is a satoshi?
A satoshi (sat) is the smallest unit of Bitcoin, named after Bitcoin's creator Satoshi Nakamoto. There are 100 million satoshis in one Bitcoin (1 BTC = 100,000,000 sats). This divisibility makes Bitcoin practical for small transactions.
How many sats can I get for $1 right now?
The amount changes constantly with Bitcoin's price. Use the calculator above to see the current rate. At around $100,000 per BTC, $1 gets you approximately 1,000 sats.
Why do Bitcoiners talk in sats instead of BTC?
As Bitcoin's price has risen, talking in whole Bitcoins becomes impractical for everyday amounts. Saying "1,000 sats" is much clearer than "0.00001 BTC." Sats also make Bitcoin feel more accessible - most people can afford thousands of sats even if they can't afford a whole Bitcoin.
What does "stacking sats" mean?
Stacking sats means regularly accumulating small amounts of Bitcoin over time, typically through dollar-cost averaging. It's a philosophy that emphasizes consistent buying regardless of price, with the goal of building a larger Bitcoin position over years.
Will sats per dollar keep decreasing?
If Bitcoin's price continues to rise over time (which is not guaranteed), then yes, each dollar will buy fewer sats. However, Bitcoin is volatile - there are periods where the price drops and your dollar temporarily buys more sats.
Is there a minimum amount of sats I can buy?
On most exchanges, you can buy very small amounts of Bitcoin. On the Lightning Network, you can transact in single satoshis. The practical minimum depends on your exchange's fees and minimums.
How many sats will exist?
There will only ever be 21 million Bitcoin, which equals 2.1 quadrillion satoshis (2,100,000,000,000,000 sats). With a growing global population, each person could theoretically own around 262,500 sats if distributed equally.
Where can I buy sats?
You can buy satoshis on any Bitcoin exchange or app: Coinbase, Cash App, Strike, River, Kraken, and many others. Some apps are specifically designed for stacking sats with automatic recurring purchases.
