Influential members of the Bitcoin community met in Hong Kong to discuss a development plan and timeline for scaling Bitcoin. The closed-door meeting included over 30 miners, service providers, and Bitcoin Core developers and was meant to address solutions to the block size debate.The meeting concluded with a public statement proposing the group's support for the new Segregated Witness functionality, and making a hard fork in the Bitcoin protocol available that would increase the block size limit between 2MB and 4MB by July 2016.Others in the Bitcoin community denounced the meeting as being inconsequential as the parties involved represented a small handful of Bitcoin companies and special interest groups.Sources: @bitcoinroundtable/bitcoin-roundtable-consensus-266d475a61ff -miners-back-proposed-timeline-for-2017-network-hard-fork/ _have_consensus_in_april_we_get_sw_3_months/
In a public blog post, Mike Hearn declared that Bitcoin had failed and that he will "no longer be taking part in Bitcoin development". Hearn was an ex-Google developer who had been heavily involved in the Bitcoin community and related projects since the early days of the cryptocurrency. His most popular project was bitcoinj, a Java implementation of the Bitcoin protocol.Hearn's post blamed Bitcoin's alleged failure on a number of reasons: censorship in the Bitcoin community, the centralization of mining to a handful of Chinese miners, and the unwillingness of Bitcoin Core developers to increase the limit on Bitcoin's block size. Within 24 hours of the post being published, Bitcoin's price dropped over $50 USD.Others in the Bitcoin community accused Hearn of purposely attacking Bitcoin in order to promote his new employer, R3 CEV, a startup focused on using blockchain technology to improve the operations of the global banking industry.Sources: @octskyward/the-resolution-of-the-bitcoin-experiment-dabb30201f7 -hearn-says-bitcoin-has-failed-and-sees-a-price-plunge-in-the-future/
Due to GHash.io's popularity and partnership with CEX.io to sell mining shares of their own mining hardware, the mining pool giant gains a sole majority of the Bitcoin network hashing power, and the ability to launch a successful 51% attack on the Bitcoin network. With a majority of the Bitcoin network hashing power, GHash.io could temporarily reverse transactions that they send (double spending) and prevent other transactions from being confirmed.GHash.io responds by stating they "have and never will participate in any 51% attack". The pool also issues a press statement declaring that it will attempt to limit its hashing power to 39.99% by "actively asking miners to take their hardware away from GHash.IO and mine on other pools", as well as form a committee to assist Bitcoin core developers in solving the 51% attack problem.Sources: -statement-on-51-threat-and-closed-round-table/ -reaching-51-network-power-bitcoin-mining-pool-says-trust-us/
Shaking confidence in Bitcoin and the validity of some transactions, the price briefly plummets and the Mt. Gox exchange temporarily suspends bitcoin deposits. Thanks to a swift and coordinated response by Bitcoin developers, miners, and community members, the fork is resolved within hours after the operators of two large mining pools, Michael Marsee (of BTC Guild) and Marek Palatinus (of slush's pool), honorably forgo some of their accumulated mining rewards in order to downgrade to the previous, compatible version. An updated version, 0.8.1, is released shortly after, containing safeguards to prevent the original problem.Sources: -03-11-chain-fork -0050.mediawiki

In May, an Elite Fixtures survey found that the average cost to mine a bitcoin in the U.S. was $4,758. But rising electricity prices and mining hardware costs would suggest this average cost has climbed. 2ff7e9595c
