Link WP PBN to WP money site?

Hello guys, after some readings I finally decided to start my own PBN, but the thing with my money site is it is also a wordpress based website.

So if I use wordpress to set up my PBN and then link it to my wordpress money site, will this cause any problem? I have been aware the tactics of hiding footprints, I was concerned because lot of people said not to inter-link PBN sites because they are all wordpress based, so does this applies to PBN-money site? I was confused.

You should not use WP for every site in your network. Mix up Joomla, WP, Drupal, Pure HTML5 etc. to reduce your footprint. And yes, don't interlink PBN links. There's no problem having a WP PBN site linking to a WP money site (a LOT of sites on the web are WP, so chances are a WP site will link to a WP site at some point), but if ALL your PBN is WP, that's leaving a footprint.
