Questions
Can I trade here?
No. There are no accounts, deposits or orders.
Why might a price differ from my exchange?
Each source updates on its own schedule, and the server cache can make data up to two minutes old.
Why do Gainers sometimes say CoinGecko, not Binance?
Binance blocks some server locations. The page then falls back to CoinGecko data and says so.
