Bitcoin dominance — bitcoin's share of the total cryptocurrency market capitalization — has been in freefall in the second half of this month after hitting year-to-date highs in mid-September.
Bitcoin's contribution to the total cryptocurrency market capitalization has dropped to just above 50% (according to CoinMarketCap data) as other major cryptocurrencies experience a revival, boosted by big wins for ripple (XRP), bitcoin cash, and litecoin.
In August, bitcoin dominance hit 50% for the first time this year after beginning 2018 at some 37% as many of the so-called altcoins that had surged throughout 2017 were heavily sold off.
Bitcoin currently has a market cap of $117 billion, down from $127 billion at the beginning of the month. Meanwhile, other major cryptocurrencies have made significant gains as a wave of positive announcements has rejuvenated trader and investor sentiment.
Despite the bitcoin price ticking up by almost 5% over the last 24 hours to some $6,700, it has not been enough to erase bitcoin's loses for September — which saw bitcoin climb to over $7,250.
The latest bitcoin price bump was sparked by a Bloomberg report suggesting a significant "positive price movement" is on the horizon — based on analysis of RIG trend lines, a leading technical indicator that is a combination of the RSI and momentum studies.
