Most Copycats failed woefully trying to replicate this forum... Those that suceeded abit failed to attract good numbers of loyal members. The forums, no matter how beautiful, are boring and depressing
The possible reason for this Forum success maybe be due to the success of Bitcoin & the niche it creates for the forum.
So rather than getting greedy & looking for means to become rich from forum ad revenue, focus more on carving out "a niche forum" other businesses/companies cannot exist without or better still create a forum the existence of other Altcoins would depend on
To be frank, I think only Ethereum founder could successfully replicate this forum due to the number of Altcoins that depend on Ethereum.
The Founder could easily unite these Altcoins under a Forum, . where they can come together to share ideas, softwares, products and services. He could go as far as making the forum impossible to avoid.. by making it mandatory for Altcoins that depend on Ethereum Network . In the end, a giant business environment where Ethereum fans and job seekers can work & earn Ethereum & Bitcoin will be created.
So, maybe focus on a business/product other companies would depend on to suceed then build a forum & gather the companies to exchange ideas, products and services.
No one can replicate this forum. This forum has the "original" aura, because satoshi posted here and it started here, a ton of historical information on bitcoin and therefore on crypto as a whole is stored here. Satoshi is often quoted in the forum here. This forum is too big to be replaced.
Just like nobody can replicate the original bitcoin, because it has that special aura with satoshi the anonymous developer, the original coin etc.
People wanting to earn ETH could search for people offering ETH in the services section here.
You can try to improve on it, but you can't replicate it.
