Thank you both for your replies. Marketplace Altcoins seems indeed the most fitting board, until there is a little seperate blockchain gaming (child) board, which I would like very much. Just like gambling with all the crypto books/casinos, the blockchain and blockchain-based gaming realm will also be helpful for BTC/crypto in general imo.
Unfortunately, there
probably isn't enough demand for this to happen. Although, the altcoin marketplace gets a fair amount of traffic, and legitimately good projects are really needed within that space in my opinion. A gambling section within the altcoin section would likely to be a more realistic goal as opposed to a Blockchain gambling section as its a little more broader.
