Hey Tim, I've seen some of your posts and of course, respect you as a fellow freelancer, we're all trying to make a living here, and we all want to try and share knowledge -- but I've always had my doubts about marketing for crypto, done the way most digital marketing is carried out.
I think actual engagement is still very difficult to achieve in the short term, and there's only so much that so-called growth hacking strategies can do for organic growth and "real" engagement.
I personally like a few brands I follow, and you can see perhaps a couple or more posts with comments in a week, but these generate a lot of further comments but they're useful and guys like me go through the entire length to read.
But overall, statistically, they have shit, close to 0% engagement. But zero spam comments.
My issue with paid marketing and growth hacking (I've tried them in the past for various small projects) is that they seem to give me the #s, but not the staying power, non-sustainable impact. And in fact, the long-term repercussion for many projects who try paid marketing is that they're left with thousands of followers who probably aren't real people OR aren't people who will ever be invested (time or effort) into the project.
OF course, I know you're talking about free marketing, and not paid. But my point is, maybe taking short cuts ends up getting you lost in the wilderness? As opposed to not marketing and just getting stuck in obscurity? =)
Marketing can only go as far as the project. If the project itself is not useful then no one will want to use it or invest time reading about it. So yeah marketing projects will fail sometimes, but that is business in general. (Most businesses don't make it)
You will always get spammed comments especially since it is crypto, however, I have found that the cryptocurrency community is extremely helpful and engaging. If you have a small project then you have to have a realistic marketing view. A small project with a marketing budget of less than $2k is not going to be a full-blown $100k plan.
This article explains how you can personally boost your project without any paid marketing unless you pay someone to do it. If you approach it in the same direction you will have success (generally), but like I said before it is the project itself.
Ex: Cryptocurrency exchanges are always starting up because there is a lot of money in transaction fees. But if you start up a crypto kitties look-alike game, it might not perform as well.
When marketing, it is important to post valuable content around your product/service and if you do that then you will be fine. This is marketing 101 but it really is important to learn. [Basically what the case study is about. Some good ideas are presented in the case study and could spark some ideas for your projects.]
