Thank you for not being a smartass in your answer.Oh man, you are just in the beginning of the journey
Save some of your time and use high quality mobile or residential proxies first of all.
And search and read bunch of conversation in this subforum, there are plenty of useful info about all those aspects.
Good luck.
I'd run 7 max on your home computer. If you have access to a neighbor's wifi, you can run 7 more. I would try to avoid purchasing proxies for any operation under 20 accounts. Just have to be creative with how to find wifi access.
