A simple, low-data price desk for Bitcoin on Blake2b. Neoxa calls it XBT. NonKYC calls it BTCB2.
The big number is an equal-weight average of the live books on those two exchanges, converted to dollars. Best price is the cheapest of those trades. Stocks, other coins, funds, and major currencies sit beside it for comparison. The average can also be shown in other currencies, using the rate from each day.
