I am going digital with comics. Save up on space.
The easy answer is the cost is what the market can bare. I am just saying those very same comics I am seeing sell for $15 right now on Ebay - the spider-verse ones - I saw at the comic book store for about a dollar over cover price - which is what they normally charge all back issues not in the dollar bin. There are just not that rare. Supply and demand. I am sure you can make money regardless - I just don't feel confident I would make money selling recent issues for so much above cover.
I am 50/50 between digital and trades. I couldn't go 100% digital even if I wanted too. I only get digital books that I can't find in print. That and I'm too accustomed to actually feeling the book with my hands, and what if my internet is down? Then I'd be really screwed.
Digital comics rejuvenated my love for the medium. I can't see myself ever returning to print versions. I fully understand the few dangers of digital readership...BUT...I'm very convinced that electricity and wifi aren't going away any time soon and the publishers from whom I purchase the most titles now offer DRM-free PDFs, so I've got a file to read even if wifi is compromised. AND...above-and-beyond all...comics are just absolutely and breathtakingly beautiful on my iPad. Although I'm not a huge environmentalist, I still think it's good that I'm not purchasing paper, backing boards, mylar bags and long boxes any more.
FWIW
I am DEFINITELY starting to think about abandoning monthlies, though. It's infinitely better to read a TBP straight through. BUT...it's hard to skip all of the nice Image, Oni Press and Valiant monthlies...
I only bothered with the 1st print, and managed to get some NM copies at cover price. The variant is selling for upwards of $200...that's one I'm not prepared to take a gamble on, I'd rather spend that money on back-issues that are tried and tested. Like silver-age Spideys in high grade.

And of Jezebel also spake the LORD, saying, The dogs shall eat Jezebel by the wall of Jezreel.
I am fairly new to collecting so my collecting habits haven't really changed. I mostly do the digital thing, Marvel from Marvel Unlimited, the rest from sales from the Google play store/Comixology. The exceptions are Ms. Marvel, books with X-23 on the cover, all Dawn books and first appearances of character's I like.
I really only buy the Ms. Marvel books for support reasons as I never even read the physical copies.
Back when there was hope comic book collecting was a good investment I liked knowing what I read had some sort of re-sale value as a validation of my reading choices. In other words, the comics I were reading must be good because others want to spend money to own them after the fact. I miss those days but I don't see them returning.

As a new reader to the digital comic book experience I will say that it has forced me to pay attention to the panel and slowed down my reading. That is a good thing. I tend to speed read and on a paper comic book I read without looking at the pictures. The way the digital arranges the word balloons within the panels forces me to slow down and look so I think that is a bonus. It looks like the digital codes I sell from my Marvel paper comics helps pay for my digital purchases via paypal this month so - so far so good with this mixed model approach of buying paper Marvel books - selling the digital codes and then getting everything else in digital.
