Started mining at the beginning of 2015 and am now up to 2.8 th/s. With BTC increasing, adding more hash requires relativity less coin. Hence, I am able to upgrade sooner and more often. Hope the price stays up for a while so I can keep building my mine.
You are not thinking logically. Please. It is more worthwhole to buy coins and hold. Alternatively, invest in other form of algorithm cloud mining, get alt coins and trade for btc
