I am thinking I will likely have to start mining the alt-coins that support ASIC miners and turning them into BTC's to get ahead, unless the amount of Bitoin's in the world increase from 11 million to whatever the next increment is. But Bitcoin will never die. 
i'm dabbling - mining SHA alt coins, trading them for BTC and ploughing it all into cloud mining - if you can't beat them, join them.
i decided to make a ceiling on my btc sell price - as soon as it dropped below 450, all btc I gather from mining is getting put straight back into my cloud contracts. by the time btc is up over that ceiling again, i'll have accrued a nice sized contract on the cloud - which will keep hashing for the duration of my contract... and still have my small rig at home to keep running as a hobby.
