In an ideal world organically growing your link profile would require both do-follow and nofollow backlinks. In your link building efforts make every effort to generate both.
I must say though that it might be a little harder to match them at 50:50 because getting do-follow links has increasingly become harder from reputable sites. Take Moz for example, I could quite easily get a nofollow to my website https://carrentaluganda.info/ but getting Moz to give you a dofollow is near impossible. So while you try to grab a bit of both to keep your profile healthy, you shouls not get furastrated at the fact that you are not attracting as much dofollows which are the main driver of link Juice. Happy hunting and cheers.
