The predictable part of this market is that when Bitcoin rises, alts rise EVEN MORE. The proliferation of alt coins and the unbreakable link to BTC effectively means infinite money printing. Every new coin that latches on is another round of quantitative easing. For BTC to rise 10%, it has to carry 40 other coins to 20% gains, and that number is only increasing.
We will NEVER see another major price rise unless this link is severed. Value increase will simply be reflected by yet more coins pegged to BTC.
