I, for one, am getting tired of bitcoin and the craziness underlying it. The last thing I want in a currency is inherent craziness.
Most of the altcoins are forks of bitcoin, or improvements of the blockchain. Some are significant improvements--Monero, litecoin, and Dash come to mind. In the case of litecoin, there is plenty of history with no craziness.
Why would I support bitcoin or any of the new baby bitcoins created from such turmoil? In the long term I'm betting on altcoins created before August 1.
