Please help me with instagram automation,proxy,etc (newbie questions)

Hi, newbie questions here. I have an instagram account right now made with my real IP through my smartphone and I've never used any kind of bots and/or automation software before. But now I want to give it a try. If I buy one instagram account (perhaps I should buy it here?) and use followliker for example, do I have to buy one dedicated proxy too? Why do I have to use proxy to run my bot? Does that proxy should match the country where my account made? Can you recommend where I should by…
