Instagram Proxies

I just need someone to explain what proxies are all about, I have read some stuff and watched videos but need a simplified breakdown of it. Few questions.

Does one proxy purchase mean - 1 instagram account or multiple.

And what is an actual proxy, A link or an actual program to change your I.P?

Thanks

Proxy is like a relay between your PC and the site, it is not a program, but access to the relay

With 1 proxy you can create one or multiple accounts depending on the websites you create accounts

The safe way is make 3 accounts per proxy per day. If you are going to use only one account, then you do not need proxies. In case you need one, you have to get a virgin Instagram proxy that has never been used before.

Bumping this thread. I'm buying an IG bot that has 1K+ accounts to like certain pics. I have read on here about proxies and whatnot. How does it work exactly?
