How are the USD values made to fit the total?

The target total is split into random weighted slices, one per asset. Each slice becomes that coin's USD value, and the quantity is value divided by its fictional price. Summing the slices returns the total, so the portfolio always adds up exactly.

What fields does each holding include?

Each row has symbol, name, quantity, priceUsd, valueUsd and change24h (a signed percentage). A portfolio summary also reports the total value and the weighted 24h change across all holdings.

Are these real coins and prices?

The symbols use well-known names for familiarity, but the prices, quantities and changes are all randomly generated placeholder data. Never present them as real market prices or real balances.

Can I export it as JSON?

Yes. A format toggle switches between a readable table and a JSON array of holding objects plus a summary, ready to paste into a fixture, API stub or charting component.

Does anything leave my browser?

No. The portfolio is generated entirely in your browser with a random number generator. Nothing is uploaded, so you can build demos offline and keep your data on your machine.

Fake Crypto Portfolio Generator

Fill a wallet dashboard with plausible holdings

A crypto wallet or DeFi dashboard demo needs holdings that add up correctly. This fake crypto portfolio generator builds a set of fictional positions with quantities, prices, USD values and 24-hour changes that sum to a target total, so balances and pie charts look right without using real account data.

How it works

You choose how many assets to hold and a target total value. The generator splits the total into random weighted slices, one per coin, so the parts always add back to the whole. Each coin gets a fictional unit price and a signed 24-hour percent change; the quantity is derived so the position matches its slice:

valueUsd = totalTarget * weight_i / sum(weights)
quantity = valueUsd / priceUsd

The summary reports the portfolio total and a value-weighted 24-hour change. Export the result as a table or as JSON.

Tips and examples

Use 3 to 5 holdings for a clean demo card, or 10 plus for a busy power-user view.
Set the total to a round figure so the headline balance reads nicely in screenshots.
Pull the JSON into a chart component to render an allocation pie that always sums to 100 percent.
