The best thing going for Bitcoin was the democracy of mining in that anybody with a graphics card can generate a small amount, now you need serious investment in ASIC kit that is unlikely to make a return. All the GPU's are now useless and so the generation phase that was anticipated in the original design has ended. Without significant market share and large transactions fees, its pointless for anybody to make an investment in mining.
So my prediction is a slow downward spiral in value from now on. Meanwhile hash rates will continue to rocket until the ASIC manufacturers start to fold resulting in one or two large miners left operating i.e. a large likelihood of the dreaded 51% scenario. Then Bitcoin will be truly worthless.
It's a real shame, I really wanted it to succeed but I think ASIC's came too soon in its life cycle and killed it.
I disagree, ASICS are populating the world, thousands and thousands of them being built and sold. Bitcoin mining is the only thing an ASIC does, once someone has an ASIC they are a guaranteed bitcoin supporter. The ASIC population of the world is setting up the basic network, the core (dispersed) infrastructure that forms the foundation of bitcoin's future.
It will just take a few years for the whole thing to be rolled out: Mass-ASICS and an upgrade of the exchanges is what's currently happening. ASICS aren't killing bitcoin at all, they are simply the foundation and they will get cheaper too, and having a network of tens of thousands of ASICS (will probably end up being hundreds of thousands) is plenty! We don't all need to be mining.
More companies developing ASICS is good news! More ASICS being built at all is good news, after all, they are BITCOIN ASICS!
