Day trading

This will sound stupid but bear with me pleas, I started learning crypto about 6 months now, its not that much and I have a lot to learn i had some successful trades in btc, ada, eth, but all of them were 15 20$ not more than that so I calculated how much I would earn if I invest 5k (in spot I don't do futures) so my income would be 50 60$ a day, this could give me live income because I live in a third world country so 60$ is a lot here, now what's the catch, cuz we all know nothing is easy so where am i wrong here. Thank you for reading.
