Question 1

What does it show?

Accepted Answer

Concentration (how much of the portfolio sits in its largest position), allocation across assets, an indexed net-worth line that starts at 100 so trends are readable without amounts, and live prices for the crypto positions.

Question 2

Why are there no amounts?

Accepted Answer

Because the amount is the part that makes people either complacent or miserable, and it is not the part that informs a decision. Weights, concentration and the distance to your own buy/sell bands are. Entering percentages also means the page never holds anything worth stealing.

Question 3

Where is the data stored?

Accepted Answer

In the browser, on the device it was typed into. There is no account, no server-side store and no sync.
