There are a few details to iron out, but is this a good business idea?
I'd recommend doing a business plan first and looking at the current competition on the market and some other factors.
1. the good news is the tech is out there working on block chains so yes you can start tomorrow with tech that will facilitate your idea free of charge or at very little start up costs.
2. I see a problem with competitors and the block chain you prefer to build on and use but this will show in your business plan up!
3. You essential want to create NFT's using the bitcoin block chain. NFT's are already out there and should be considers your competition. Marketing plan should include that. What's in your business and marketing plan about competition and how you approach is better ?
4. If your idea takes off you will run in some problems your business plan will show. The speed of the BTC chain and the very high costs. I'd recommend looking at other block chains that are currently being used for NFT's such as Ethereum, Solana, BNB much cheaper, fast and more scalable.
5. While going for it you need to build a brand and should consider a custom token for your brand maybe a Marky Mark Token which could become very collectible if you limit supple and use it to facilitate your transactions. With a strong Branding and Marketing you could use your Marky Mark Token to initial founding ( early investors ) your project and take a cut on each NFT transaction. With your background in finance you should be able to run a proper liquid . exchange.
6. After that you wanna think big and create your own exchange and block chain to get a cut on each transaction. Digital real estate could become and extra source of income to hang out for all those Marky Mark Token holders. Have a chat and see if Snoop Dog wants to buy in and become a neighbour. He's doing really well in that field and people pay good money to be his neighbour online.
7. Once up and running you wanna work on "WORLD-CLASS PARTNERSHIPS"
with possible partnerships of existing brands. Google, Universal Movies and so on.
Your idea reminds me a bit of doge coin " Dogecoin Started as a Joke. Now It’s Too Important to Laugh Off " with a 10 Billion market cap. It went down a bit from 80 billion but there is always good times and bad times.
Doge coin started like this on a forum as a joke and bang 9 years later it had 80 billion cap. Your idea might not be as crazy as people might think!
As crazy as it all sounds this can be done as the tech is freely available to facility your idea by tomorrow. I reckon if you post an offer on here some people would actually buy your initial Token to found the project.
It all comes down as we all know to a rock solid business plan and marketing plan. Maybe we can get Ozzy on board and get our own section on UKBF.
