How to deal with AMP and original backlinks

Hey guys, I'm thinking to make AMP page with my main page but don't no how to deal with original backlinks.

I'm planning to use AMP plugin.

You know, if my site is http://www.example.com and my amp page would be http://www.example.com/amp, right?

The point is "I don't want to loose my backlinks that linking to my original main page".

And should I have to do 301 redirect my main_page -> main_page/amp?
or should I just leave both main_page and main_page/amp and google will do the rest?

I have searched on the internet but everyone is talking about "Pros and Cons about AMP" not details about how to do it.

Can anyone explain this for me?

dont bother going with amp. stupid idea by google, which they came out and said that they no longer will use it as a signal on what to show on the carousel section.

see this: https://www.searchenginejournal.com/google-page-experience-update-begins-rolling-out/

As part of this update, AMP is no longer a requirement for pages to be included in the Top Stories carousel. That change will take effect as early as this Thursday. In addition, Google is expanding the usage of non-AMP content to Google News and removing the AMP badge icon from search results.

AMP can make it easy to deliver on all the page experience related criteria.
You could make redirects to it, that enables a good user impression on landing page.
If your content non-AMP, it will be pulled into the top stories carousel as long as it meets Google News policies.

don't bother going with amp, this is one of the too many problems that you'll get using it (you can search for a bunch of them),
having a responsive theme along with caching (server & user sides) will usually do the work without any kind of problems
