[Optimism] - NFT Crossovers
Bounty Question
> Create a dashboard that shows the crossover between the Optimism OP NFT projects by market cap. Which of the strongest projects tend to have the most crossover, and which projects have a wider mix of other communities? Which communities tend to provide the most signal that another NFT project will do well? As in, is there any alpha if you were to see a certain PFP buying another collection? Which communities tend to be most active in minting new collections? Which communities have are the most diamond handed on other projects?
Why focus on NFT Crypto Community
> ## The NFT crypto community refers to a group of people that are actively collecting, trading, selling, and engaging in conversations about Non-Fungible Tokens or NFTs. A creative who shares links to their art or project shill their NFTs. Those who buy NFTs and resell them for a profit are called flippers. > > ## Building an NFT crypto community from the very beginning is crucial. Not only does a strong community set the foundations for a successful NFTs sale, but it can also generate buzz that attracts buy-in—and bring additional traffic to your profile. > > ## Indeed, NFTs are evolving to the point where you either now need to offer a service or a community. For instance, some projects are offering tokens where holders get exposure to a range of NFTs. Investors need to know that there’s a credible team behind the project and a community around it. They also want to follow the journey of the project closely and be assured that the team behind the NFT is in it for the long term. > > ## SuperRare, for instance, is a curated NFT crypto community with onboarding policies and quality guidelines for artists and collectors. This helps to attract like-minded people to their platform, creating a sort of informal social layer that facilitates buying and selling more than anything else. > > ## If your community is large and strong enough, your project will quickly gather interest from both investors, fans, and the press. It is therefore critical to build your audience from early on. The community approach provides you with the opportunity to build a strong network of relations amongst the blockchain ecosystem.

Methodology
> First, through this link, the top 5 collections in terms of sales volume over time were determined, and in the screenshot taken from this list, which follows, you can see these 5 collections and their sales volume over time:

> Then, the addresses of these collections were found at optimistic.etherscan.io, and due to these addresses, the review on these collections was started. To check these collections, a basic query was used, which is as follows:
select
BLOCK_TIMESTAMP,
TX_HASH,
SELLER_ADDRESS,
BUYER_ADDRESS,
nft_Address,
case
when nft_Address = lower('0x0110Bb5739a6F82eafc748418e572Fc67d854a0F') then 'Early Optimists'
when nft_Address = lower('0xB8Df6Cc3050cC02F967Db1eE48330bA23276A492') then 'OptiPunks'

when nft_Address = lower('0xA95579592078783B409803Ddc75Bb402C217A924') then 'Hello World'
