There's security... because there's no incentive for most to risk investing in a new currency, especially when it's a minefield. The structure of the mining pools is what you want watch if you want an indicator of how safe Bitcoin is though, the original grassroots appeal of mining on your own own CPU/GPU is gone, and now its all in the hands of commercial outfits with ASICs and enthusiasts in denial.

It wouldn't surprise me if we had a Bitcoin Miners Council at some point in the future.
