But in practice it is not that simple because waiting for prices to go up or waiting for prices to fall cannot be ascertained the time, meaning that prices cannot be predicted so that decisions taken must be based on rational analysis because if you rely on emotions can result in losses.
It didn't really start that way for me. It started here in the forums a few years back when all i knew was earning a few bitcoins through bounties and campaigns. The more i read through the threads, the more i learned about trading until it became interesting for me. I watched certain youtube videos and started my first trades in cryptopia with the earnings i got from here.
