Trading bots are mostly scams... but there are exceptions. You just need a lot a patience to backtest and run many bots, discard the ones that are scams and keep playing with the ones that are good. EDIT: since so many of you ask, yes I use Galileo FX.. .

Hello ive always watching your videos every night and ive learned a lot, i just want to suggest can you make a tutorial on how to make a minting button in a existing smart contract? I'm currently studying Webflow functions and i had a idea to lessen dev works. I'n a way of making a finish mint button and all you need to do is paste the embedded minting button code on webflow and after published it the minting button will appear. I just want to ask is it possible to make? sorry im a noobie dev and I spent days watching and learning in YT and never seen anyone make those kind of method. Anyways thank you so much for making a lots of tutorial about building in WEB 3, never seen any youtuber so consistent like you helping us like me struggling on learning WEB3 codes. Hope you notice my Message THANK YOU SO MUCH

how can i connect this bot to Flash loans?

[@sunshinetrain43]

I want to be able to query pairs at the same dex. I simply made the routes as they are for the dual dex trade (router, router, token, token) but with the two routers being the same. I am not getting any "hits" on this and not sure if it's because I need to write it differently or if there just are no trades to be made. I'm enjoying the experimentation with this either way!
