How Metamorphoses Sold Out 3 NFT Collections with a 92% CPA Reduction on Blockchain-Ads

Build qualified whitelist and drive sold-out status for three consecutive NFT collections
Concept2048 is a premium fashion brand that launched Metamorphoses, an exclusive art NFT collection on the TON blockchain combining handmade physical artworks with digital ownership. Each piece carries a 0.2 ETH floor price, positioning the collection firmly in the premium collector segment. Concept2048 ran a six-month campaign on Blockchain-Ads to build a qualified Telegram whitelist and achieve sold-out status across three consecutive collection releases.
A note on attribution: Concept2048's paid acquisition on Blockchain-Ads is managed through affiliate partners, each running independently with their own market focus and creative approach. This case study covers one such campaign and reflects what Blockchain-Ads can deliver for Concept2048-aligned partners targeting premium crypto collectors across Western Europe, North America, and Southeast Asia.
Concept2048 needed to reach crypto collectors with both the financial capacity to purchase at a 0.2 ETH floor price and the cultural context to appreciate handmade art transitioning to blockchain ownership. This had to happen across three consecutive sellout windows over six months. Three obstacles defined what that required:
Key Obstacles
Standard programmatic networks could not identify ETH holders with sufficient portfolio value to meet the 0.2 ETH floor price requirement. They also could not distinguish premium art collectors from general NFT speculators. Concept2048 needed a platform capable of reaching verified high-net-worth crypto investors and building a sequential whitelist-to-mint funnel across three collection windows. Blockchain-Ads provided that through three capabilities:
The campaign launched across HNWI and ETH Holder segments with Personal Finance and Investing interest overlays. This was a cold audience with no prior exposure to the Metamorphoses brand, so creative led with whitelist entry as the primary conversion action. Angles like Join the Metamorphoses NFTs Whitelist introduced the collection and drove initial Telegram community entry. Opening CPA sat at $104 across 225 whitelist entries as the algorithm established performance data against a new premium collector audience. Collection 1 sold out from this initial whitelist build.
Collection 2 activated retargeting against users who had engaged with Collection 1 but had not yet minted. It simultaneously prospected new HNWI and ETH Holder audiences. The warm retargeting base drove immediate CPA improvement, falling from $104 to $49, a 53% reduction. Creative shifted toward social proof and craft authenticity. Angles referencing four pre-sales sold out on Telegram and Concept2048's handmade artworks becoming NFTs reinforced both demand signal and physical art provenance. Collection 2 sold out, with 901 whitelist entries delivered across the phase.
The third collection scaled the accumulated audience pool from six months of whitelist building and retargeting. The sold-out pre-mint angle ran against new cold audiences. Prior collection participants received retargeting creative referencing the established sellout track record. The compounded retargeting base drove CPA from $49 to $7.99, an 84% reduction in the final phase alone. The campaign closed with 10,134 whitelist entries in Phase 3 and 11,260 total across the full six months. Total CPA reduction reached 92% from the Phase 1 starting point. Collection 3 sold out.
