In the event that you were actually interested in corresponding, yes, I do mine a variety of coins. In fact, I haven't specifically mined BTC for quite some time as a primary coin and that has turned out well for me. However I don't consider it dead, rather a fallback in the event other coins are not profitable for me, as they sometimes are not. Other coins I will continue to mine as "fairweather", like LTC PPLNS, but I have other miners I switch around based on RBPPS systems generally speaking. Not sure what you mean about mining "dead coins", to which coins are you referring to? A lot of assumptions! Just ask, the information comes out easier. I have more than one miner.
To me, LTC is past dead and some people just cant do the math because they are stuck on their dreams of the future of LTC.
BTC is alive to ASIC, and alive to GPU if you are confident you wont break a GPU in the process. If you do burn one out, you just lost money you will never get back at this rate of difficulty increase and ASIC taking over.
