When starting your Warrior Trading Bot you choose the base currency with which the bot will trade. 
If you select euro then that is your base currency and your bot can only buy cryptocurrencies with your base currency.
If you have selected euro as your base currency and you only have USD, BTC or any other currency besides euro for example, your bot simply can not trade. 


Our bot supports at least following base coins:
AUD
BTC
CAD
CHF
DAI
ETH
EUR
GBP
JPY
USD
USDC
USDT


It all depends on whether your chosen exchange supports the trade pairs you want.
Eg: Kucoin does not support EUR as basecoin.


We however recommend to use only following base coins:
- If you are living in Europe: EUR
- If you are living in the US: USD

Motivation
  1. BTC has a higher transaction cost, as such results will be lower.
  2. You know your coin the best. If you live in Europe and use USD as a base currency, then while you are sleeping shocks could occur to USD.
    As you do not live there and do not follow their news, you are always later to respond than people living in the US.
    This results in needless risks. Use your own coin, you know it best.
  3. Some of these coins do not have enough volume to trade fast and succesfully.
    If you cannot sell quickly when you have profit, you risk the coin dropping while you wait for your sell transaction to be processed.
