Posted by SlipperySlope: When bitcoin prices eventually explosively rally again as suggested by the logistic model trendline, it is very likely that the most-popular-at-the-time scrypt-based coins will exceed the price acceleration of bitcoin, i.e. have a higher beta.
These younger coins are at an earlier point on their own unique S curve, mirroring Bitcoin from perhaps 2010. Their price movements come as less of a surprise as Bitcoin blazes the pricing trail. Looking at Litecoin which has been around for as long as any other alt coin, price has retreated (23 todays avg) from the high (42 apx high) almost 50%. Bitcoin appears to be settling about 25% down from the high near 1200's.
I believe mining the alt coins is beneficial to Bitcoin and welcome the alt coins in fact. DOGE coin has introduced thousands of new users who can learn and experience cryptocurrency with little to no risk.
Leadership from Bitcoin, innovation from the Altcoins. I wonder what consolidation among coins will look like? I hope enthusiasts discover methods of gracefully merging those deserving more than abandonment. Nothing sadder than pulling up a QT wallet and finding no peers.
