Hello good, because long ago I'm thinking begin to undermine what I'm not sure is whether undermine today Bitcoins or litecoin, which is the most profitable that is say an example I start to undermine Litecoins with an ASIC of 5.2 mh / s to mine Bitcoins start with ASIC 63 or 400/500 gh / s, the truth is not good to do. Recomendarais I'd like to do and how to recover the initial investment made in the ASIC and earn more, thanks.
Sorry for my english... (Google translator 70% xD)
I think that is not worth to mine. Price of ASIC to high + electricity + difficulty rising every 14 days. make you investment very hard to be recovered. To not speak for profits.
