Of course, there’s more to Bitcoin than the three stated parts. Exchanges, mixers and block explorers are but a few new domains within the Bitcoin industry that didn’t exist in 2009. This specialization is likely a net benefit, but also holds downsides, particularly for an industry already within the regulatory cross-hairs. An attack on one part, say proof-of-work (PoW) mining, will bleed into other areas of Bitcoin, such as privacy.
