What is community?
I think the reward halving might have devastating consequences on the Bitcoin ecosystem. People seem to forget that Bitcoin is not just a digital currency. It is also a payment system which is backing up this currency, and its success (or failure) predetermines Bitcoin's ultimate destiny as money...
I just thought we are generating too much hype. On one side I can see people predicting we will get to see an eventual increase in the price while the other side, looking at a total failure of the whole system, if that was what I tried to intrepret from your conversation.
Whatever the condition, I think it will eventually balanced out. If a miner finds it hard to maintain profitability and dropped out, there will always be others who will know how to operate efficiently to cover the mining cost. Provided that demand for the coins remains strong, this will also have positive effect on the price. Thus whatever the scenario, bitcoin will survive through.
