(day)trading; what, where and how often

[Zaquess]

Hello, I'm kinda new in crypto and from all of you and from every one of you i want to hear opinion and trading strategy because i believe that every one do the trading different by itsself. I know as i saw on cryptoexchanges a lot of people have automatic sell/buy orders made by their bot-because of which I cant get even close to do the trade or even better said-it is always one step before me. Which currency is the most profitable for day-two or even better said short trading, and which exchange do you prefer to trade with? To avoid high fees and to come close to high percentage of well done trade. Maybe suggesting any book to read, any channels to watch or any webpage to follow to educate? Thank you, greetings
