You do not even have to understand charts to understand where bitcoin rallies and where bitcoin drops at this stage. We have seen bitcoin moving to same prices over and over again so many times that anyone that sells at 4200 will profit when the price goes down and anyone buying at 3600 will be profiting.
I did it twice already and made a decent profit back, 4200 was the top it can see and I realized it at third time price went down after reaching 4200, so I said next time I see 4200 I will sell, also when the price hits 3600 its harder to go back down and usually goes higher so I said I will buy next time it hits 3600.

Never looked at any charts neither, was just too obvious.

Sounds a lot like beginner's luck. I'm sure you'll find over time that trading is infinitely more difficult than you make it sound.
I'm also not sure how you sold $4,200 and bought $3,600 twice since price only bounced between those extremes once.....
Using charts may increase our chance of profits and also will help us understand what our coins is actually doing but many people just doing crypto trading as pure gambling.
