I'm usually using stable coins for my trading pair, but when market progress is good, I will choose top coins such Ethereum, BNB , Bitcoin.
Stable coins are better to calculate loss or profit, but top coins such Ethereum is also good to gain double profit when crypto market show good progress.
Everything is depending in your comfort
Me too,at the beginning do trade, I always use stable coins for my trading pair.
But lately I used BNB in binance, to reduce transaction fee.
also to gain double profit if BNB price goes up.
ETH and BTC are also good for trading pair.
But You must calculate your profit.
Set the target and do trading.
I have asked several senior, they said better to use top coins such as BTC and ETH for trading pair.
