Does anyone see AMP Caching hurting their ranking?

I've been researching AMP Caching and TBH I haven't got my head around it 100% as I get confused regarding links and URL's. As I think AMP Caching will change the origin URL (I think?). So would this cause any problems with back linking !!

When you use amp you loose link juice because in title google.amp comes so backlinks loose powrr

I've removed AMP for now. Breaks styling and google cached their URL over mine
