Hello,
I am a noob in the cryptoworld.. ..and need some help:

I really wonder, why i cant use such pairs with gunbot: USD-BTC, USD-LTC, USD-XPR, USD-BCC...etc.  ?

In the moment, i have to predict every time where the price of FIAT-BTC will go, because my money are kept in BTC on Bittrex !....and if a huge BTC dump appear i will lose everything i made with the gunbot ?

Is my logic right ?

Thanks in advance!
