if you want to make a successful trade then bitcoin is much more good than other currency there is maximum people are trading in bitcoin nowadays because bitcoin is very strong and useful currency and bitcoin increasing its price too much faster than other currency.
if we make trading in bitcoin with fiat, then i think its not good unless we have a big money to do because to make 0.1 bitcoin is need a time to trading over and over, but i think if we are trading with altcoin pair btc then its more easy than trading btc with fiat.
