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.
