Altcoin prices, explained

What does a coin price really mean?

Pick a coin and try a price. See how large that coin's market would need to be, and what your own coins might be worth. These are simple what-if calculations, not predictions.

01 / Look at the market

A quick view of nine altcoins. Prices can change fast; check the update time below.

Waiting for market data

Data provided by CoinGecko. “Market value” means price × coins in circulation; “24h trading” is reported trading activity, not a promise you can sell at that price.

02 / Try a price

What if this coin reaches…?

Choose a coin and enter a possible future price. We use CoinGecko's current supply figure automatically.

Current coin data will appear here.

Supply comes from CoinGecko and is shown for context. You do not need to enter or change it.

Your what-if result—

Market value needed at that price

—Change from today's price
—Supply already circulating

Choose a coin to see its supply context.

Example: if 100 million coins circulate, a $1 coin price implies a $100 million market value. The calculation does not say that price will happen.

03 / Check your coins

What would my coins be worth?

Use the coin and possible price from the calculator above. Enter only the numbers you know about your own holding.

At your what-if price—

Possible holding value before fees and taxes

—Value at today's price
—What you paid
—Possible gain or loss
04 / Understand the result

Three things to remember

Use these checks before deciding that a coin looks “cheap.”

01 / SIZE

Price is not the whole story

Multiply price by coins in circulation to compare the size of different coin markets.

02 / SUPPLY

More coins may arrive

Some coins are not circulating yet. Future releases can change supply and affect the value of each coin.

03 / TRADING

A quote is not a sale

Trading volume gives context, but a displayed price does not guarantee you can sell a large holding at that price.

These tools show arithmetic based on a snapshot. They do not forecast future prices or account for taxes, fees, or changes in circulating supply.
Mining worksheet

Compare two coins after power costs

Only for GPU miners. The example numbers are placeholders. Use your own wall-power measurements and estimated daily mining revenue.

Scenario A · current coin

Scenario B · possible switch

Include lost earnings during stop/start and any setup cost.

Net estimate · after electricity and feeKeep A for now

B's estimated daily gain is below the required $0.20 threshold, and the one-time switching cost is not recovered within 24 hours.

$0.58A net / day
$0.77B net / day
+$0.19B − A / day

Estimated switch-cost recovery: 31.8 hours.

These are calculations on your inputs. Price, network difficulty, accepted shares, pool uptime, and fees can change. A stale or guessed input should pause a switching decision.
Formula

Show your work

gross_for_hours = gross_24h × hours / 24

electricity = wall_watts / 1000 × hours × $/kWh

net = gross_for_hours × (1 − fee%) − electricity

For B, compare net per day with A. If B is higher, divide the one-time switch cost by B's extra net per mining hour to estimate a recovery time.

Before acting

Three evidence gates

Fresh inputs: timestamp the coin price, network difficulty, and pool status.

Measured operation: use actual accepted shares and wall power from your rig, not only a benchmark.

Safe switching: require a meaningful net gain and enough dwell time to recover stop/start losses; verify the old miner stopped before a new one starts.
