I think it's worth considering whether sending traffic to signup.hive.io could be detrimental versus sending direct to one or two qualified account providers such as eCency or HiveOnboard. The general signup site has always created one extra layer of friction and can be somewhat off putting if viewers see certain sites listing a signup fee.
If a campaign landing page funnels to a specific signup partner, this would also open the door to inviting the user to input a campaign specific referral or promo code to facilitate better conversion tracking and perhaps reward new accounts with small delegations, eCency points, etc.

edit thought - It would be interesting if the funnel could target device. Example: Send direct to HiveOnboard when on desktop as their process I believe has a focus on keychain installation… while users on mobile are sent to eCency due to its more app based approach.
