I understand that blockchain and decentralization move together and for that matter, more forums for cryptocurrencies discussion should not be a big an issue but with the recent scam projects ongoing, my opinion is the leave everything in the hands of one forum to handle all ICOs discussion there.
That is not necessary to have another forum for Bitcoin talk as we can see here is well organized and moderators are functioning well with their works and the other people involved are really doing their job, if there is another forum which is similar to these, I think I will stay on here .
