I don't think so we need more forums that can spread the knowledge and the technology behind Cryptocurrency, if we want more people coming in this industry we need to build more community, we need to build more network, each forum can work to support each other and be decentralized, we have so many coins in the market and each has it's own function and roadmap and so are forums and community.
Stand to be corrected why do we think it may not be necessary as time to come as many will likely join or engage on the forum for knowledge beside there is no specific limit to which the forum need accommodate, as to limit what will be necessary for more expansion as it may bring into the system more people. Is the consideration not necessary to enable the passage of information and more spread.
