As Bitcoin breaks $12,000 per BTC, market sentiment for Bitcoin is at a yearly high. After just breaking through the major resistance level of $10,000, Bitcoin has shown no signs of slowing down as it breaks the $12,000 barrier today. This bull run and market sentiment are applying to other major cryptocurrencies, such as Ethereum and Ripple, who are also up 26% and 42% just last week. Bitcoin's overall market dominance has also been dropping, falling to 60.9%, indicating that altcoins and "alt season" may be increasing on the horizon. On a much more negative note, Ethereum Classic suffered from a 51% attack, with hackers taking control of over $5.6 million ETC from the attack. The attackers only needed $192,000 to get the required hashing power in order to orchestrate this attack. In other news, Goldman Sachs, a vocal opponent and past advocate against cryptocurrency are in talks of releasing their very own stablecoin. Goldman Sachs has changed their opinion and has decided it would like to promote innovation in the digital asset and blockchain space. In Goldman Sach's opinion, there will be a massive transition over the next decade where most financial tools will be on the blockchain.
