I will preface by making it clear that I still don't understand the intricacies of trading, I just now that on one DEX, a crypto is worth a certain amount and on another DEX that same crypto is worth a couple cents more or a couple cents less. Is A is worth $1 on DEX 1 and A is also worth $1.05 on DEX 2 then buying A on DEX 1 and selling A on DEX 2 yields 5 cents. This process can just be automated easily to be done hundreds of times no? Even if you are accounting for trading fees, you can write a bot to calculate trading fees and determine if the trade is still profitable after. What am I missing here? I'm not even aiming for insane profits, just a profit in general (maybe $1-$5 a day)

Also if you don't mind could you share how you started to learn about crypto and trading? What resources did you use and how would you recommend a beginner to get started? I'm 20 years old so I don't have very much money but I'm trying to find out if crypto is a good way to earn a lot lol
