So I think you should create and "Official altcoin", related with Bitcoin, with some inflation options, managed by the same community. That alt must be "cheap" and must has a real estable value to support a massive selling pressure. The alt would be build over a Community Central Bank.
Such a coin already exists and is doing pretty well:
NuBits. It's the first cryptocurrency that solved the volatility problem and has been holding a 1$ per nubit price peg for 10 months already since it was created.
