How it works

Two ways to ask “what if”. Here’s an example with ETH and BTC.

Market cap

What if ETH had BTC's market cap?

We give ETH the same market cap as BTC, then divide by the supply used for ETH. NOW uses the current market cap of BTC; ATH uses its historical high.

Peak ratio

What if ETH hit its peak BTC ratio?

We find the highest recorded ETH/BTC price ratio in our available daily history, then apply it to the price of BTC today. This shows what one ETH would cost if it regained that relative strength.

Use the question below your result to flip between the two modes.

What if A had B's market cap?
