We at GSMG speak of a "base" and "target" currency when we define a "trade pair" or a "market". For example, in the trading pair ADA/BTC, we call ADA the "target" currency and BTC the "base" currency.
However, the "rest of the world" calls ADA the "base" currency (!) and BTC the quote currency. BTC is called "quote" currency since it is the currency in which the price of the ADA is "quoted".
The way we do it at GSMG is thus contrary to how the rest of the world does it.
The historical reason is that we copied this definition from Bittrex back in the day.
At some point, we will conform to the rest of the world, just like Bittrex did a while ago.
Until then, please bear with us.
