It's a learnable skill though. It's not a gift, it's something you can work on.
Trading is easy to learn but hard to earn. and its always depends in the altcoin or bitcoin how you can make a good profit..
Agree with this , earning on trading is so hard because we cant predict anytime regarding on the movement of the price. You are right it realy depends on the alycoin you would buy since there are lots of coins out there to choose from which is somehow difficult to select sometimes because most of them are just scam coins.
You can still profit from scam coins.
