Most of the campaigns launched here on the forum is majorly casinos and exchanges and I've not seen a service like wallet recovery launching a campaign. If this happens then that would be the first time I will be seeing a wallet recovery service a running signature campaign. The best thing any wallet recovery service can do is to make sure they build their reputation and be active in this forum to answer users inquiries.
Yes, they have to concentrate on building larger customer bases, gaining the trust of potential clients has more importance than trying to launch a signature campaign, plus a wallet needs to need password recovery before companies like this can get customers and launching a signature campaign without knowing the exact or a relatively good number of potential clients that they are going to have, attention should be more on what they can offer, a good company's work advertises itself without stress, and word of mouth goes a long way to boost customer confidence in companies like this.
Don't you think launching a signature campaign is a way of attracting customers to themselves here in the forum, why do you think those casinos and exchanges are launching campaign here? If not to get more traffics from here to their sites, some members of this community wearing their avatar and sig or personal texts would cause other members to be curious and try to know more about the KeychainX and even patronise them if they have any issues relating with the service KeychainX offers, don't you think about it, a company that offers such service and have a campaign here and the one that doesn't, which would you patronize? Owning a campaign is even a form of building reputation and advertising their service better.
Signature campaigns are useful for long term exposure good for companies with regular clients based like casinos and exchanges, with services like this the same person can purchase their service more than once in a day but services like wallet recovery company rely on trust and credibility which needs time to build and a single person won't necessarily require their service on a regular unless you plan on losing your password on a daily which is next to impossible for anybody, plus running a signature campaign can be expensive and needs regular actual patronage from client to keep hope alive.
