At the time of this post, GHash.io controls 40% of the hashrate. The pool that’s “trusted by 180k users” is becoming dangerously big. If anyone controls over 50% of the network hashrate, he/she can likely successfully double spend his/her bitcoins, which would have a domino effect that could destroy Bitcoin. Bitcoin was designed to be decentralised, and it’s important to ensure that no entity gains too much control over the network. Please consider moving to a smaller pool or using P2Pool to avoid the threat of a 51% attack.

This app supports Quark, Mintcoin, Reddcoin
Those were the words of eBay CEO John Donahoe. When discussing the future of his company, Donahoe showed a positive but cautious outlook on bitcoin and other cryptocurrencies. This should come as no surprise to those who have been following recent Bitcoin news. Back in April, eBay added a virtual currency category to its website. Overall, it’s exciting to see eBay and PayPal getting closer to integrating with bitcoin.
