Yea the volatility of the altcoin maybe is the key factor for trading but there are still 3 important questions we can ask for the trade.
1- Which altcoins do you prefer for your daily or short time trade generally?
2- And why do you prefer?
3- Do you have any daily income goal or you trade as much as you can with this altcoins?
1 iam prefered ethereum, monero, litecoin, and xrp
2 because high volume transaction so very fast can take profit in short time trade
3 my goal in profit altcoin trading not daily but monthly, my goal in profit 100%/month
This, only high volume coins and fast trading I use bots.
