My question is, is it that possible for a beginner to start making profits from trading within 7-14 days?
If he/she bought the asset during the right time, yes.
If he/she bought the asset during the wrong time, no.
¯\_(ツ)_/¯
Have you played a casino game before? It's going to be the same. You play a game with a house edge. You're a long term loser, but sometimes you could get lucky.

Well said. If he has been hodling ever since and yet it’s only now he decides to trade, then he’ll be making profits definitely.
