Bitcoin’s dominance, that had risen above 71% in the past week is showing signs of cooling down. It has currently dropped below 70%. This implies that, for a few days, the action might shift to altcoins. However, this period of low volatility is unlikely to continue for long because after the Bakkt launch, both bulls and bears will attempt to establish their supremacy. This will result in increased volatility and a trending move.
Ripple positions itself as a complement to, rather than a competitor with, Bitcoin - the site has a page dedicated to Ripple for bitcoiners. Ripple is a distributed network which means transactions occur immediately across the network - and as it is peer to peer - the network is resilient to systemic risk. Ripples aren't mined - unlike bitcoin and its peers - but each transaction destroys a small amount of XRP which adds a deflationary measure into the system.
