This page explains the live data flow behind the converter, what the rates represent, how often they refresh, and where the product’s limits begin. The goal is simple: reference pricing should come with plain-English operational context.
cryptos.sg loads live market data for the top 30 cryptocurrencies by market capitalisation, uses USD as the common reference currency, and derives crypto-to-crypto conversions from those live USD prices inside the browser.
The homepage fetches live market data from CoinGecko’s coins markets endpoint. That payload supplies token names, symbols, ranks, images, current USD prices, and market-cap information used throughout the converter experience.
The converter loads the current top 30 cryptocurrencies by market capitalisation from the live dataset. If a token falls out of the live top 30, it may no longer appear in the default token universe until it returns to that ranking set.
The live data request runs on initial page load and then refreshes every 60 seconds. The interface also updates the visible “Updated” label between fetches so users can see how recent the currently loaded reference snapshot is.
If a live refresh fails, cryptos.sg may use the last locally cached market payload stored in the browser. This keeps the product usable during temporary fetch issues, but the site labels the data as last available rather than pretending it is a fresh live pull.
