Who runs NokxiHub

NokxiHub is a personal website published by Yann Avondo, a web developer based in France. He builds the calculation engines, maintains the market data pipelines and reviews every page before it goes live. The site launched in 2025 as AllSimulator and became NokxiHub in 2026.

There is no hidden newsroom: it is a single publisher, using AI tools to help draft and translate content. Every page is checked against its sources before publication. Most of the site is written in French for French savers; the English section only covers tools that are useful wherever you live.

How the numbers are calculated

What if I invested

  • Real prices: monthly closing prices from Yahoo Finance, refreshed every day. Intra-month highs and lows are smoothed out.
  • Real exchange rates: every purchase and every valuation is converted at that month's exchange rate, so a US stock can gain less in euros than in dollars.
  • Price only by default: the "Reinvest dividends" option switches to the price adjusted for dividends and stock splits, the closest measure of what a shareholder actually earned.
  • Gross figures: results are before brokerage fees, fund fees and taxes.

The amounts and options you enter never leave your browser: the scenario is computed on your device. Try it on the investment time machine.

Big Mac Index and Bitcoin history

The Big Mac Index uses the dataset published by The Economist, rebased on the US dollar and updated with each new edition. The history of Bitcoin relies on public price records and dated primary sources, such as the 2008 white paper. Live prices come from Yahoo Finance and Finnhub, for information only, with no guarantee of timeliness.

Independence

NokxiHub is not paid by any bank, broker or fund issuer. There are no ads, no affiliate links and no sponsored content. When a product is mentioned, it is because it is representative of the market, not because it pays.

NokxiHub does not provide investment advice. Its content is educational and general: it does not take your personal situation into account, and past performance does not predict future returns. Before making a decision, check with the institution concerned or a licensed adviser.
