I've a different theory, a Bitcoin crash will skyrocket Alt-Coins, specially ETH & XMR.
Bitcooin has a 2big issue: mining & Chinese miners, as collateral Bitcoin transaction cost has become unpopular driving users to Altcoins.
ETH isn't see now as a failed experiment, but as a resilent coin will be the one winning the most CAP from bitcoin stampeede.
This could be what a reasonablemind could say, but think about this : altcoins have no purpose. Absolutely no altcoin can permit you to buy food or car or hardware. So this reason must be taken outside of the debate. Chinese miners are not a problem, as there is no proof they are located in China (majority of the miners, not the Chinese miners). A Bitcoin transaction is not very expensive. If you can not even pay a 0,1 mBTC fee, you have greatest problems than Bitcoin.
