When primary coin is not BTC, BTC_TRADING_LIMIT is the new primary coin, USDT in your case,

So as long as you have USDT_XRP, and the BTC_TRADING_LIMIT set correctly it should work as intended.
"BTC_TRADING_LIMIT": 41.48, would be 0.01 at the current exchange rate.
Note that I don't trade other currency pairs so this is only from what Iv'e read, no practical experience
