The main goal of making the V2 collection was for people to bring money to the developer
Low.
With the launch of the second collection, a number of problems arise:
People had the association ''Index Brokers nft = INDEX token''.
With a second collection, that connection is gone. The two collections wonβt grow together, one will only get in the way of the other.
You were gone for long enough that most people have forgotten about the first collection. Only a small core of people still remembers it. You wonβt attract enough attention for people to mint V2, especially not if it isn't free.
People won't mint an NFT even for $1 if they feel like there's something suspicious going on.
You didnt even airdrop V2 to holders of the first collection. Do you really think even half of them will claim their V2 NFTs?
The silence was more successful than what you've done.
