No I don't think so, that With WWW, or without WWW you will lose Link Juice the main thing is that Which Domain is pointed like for my client I used both technique https://www.hydrogenwatermaker.net and without www like https://hydrogenwatermaker.net but it does not mean I'm afraid of Link Juice my link Juice will pass to other article as well, I am doing this for anchor distribution that Google will plenty my site , You can also make backlink with https:// or with https:// also, but the concern is same to the main Domain .
