Bitcoin’s (BTC) parabolic advance over $12,000 has taken its market dominance above 60% for the first time since April 2017, data from CoinMarketCap confirmed on June 26.

Following its rapid appreciation in recent days, the bitcoin price reached levels not seen since immediately after the end of its 2017 bull run.

The successes have come at the expense of altcoins, which have so far failed to produce similar performance. As a result, BTC dominance of the overall cryptocurrency market cap is now 62% – more than at any time in the past two years.

On the back of 12.5% daily gains at press time, BTC/USD is outperforming even the next best option in the top ten cryptocurrencies, ethereum (ETH). The latter put in 6.2% returns in the same period, its market cap still spiking above $35 billion for the first time since August.
