Brohim, you should read Satoshi's whitepaper again. Splitting the network and ecosystem in two and having 2 bitcoins sharing or shaming the brand is not the way to go. What's to stop someone from splintering it into 4 or more? Would you like to see 8 bitcoins? Would that coddle your coexist feelers?
By design and for the best interest of Bitcoin's long-term survival, the short chain will be [naturally] killed off as outlined in Satoshi's original paper/vision.

It was not the case for Ethereum and Ethereum Classic though. This makes me wonder what Satoshi's thoughts are and how that could possibly happen to Bitcoin. Before the Ethereum split, was it supposed to happen in practice?
