First of all, past increases in price shouldn't be used to calculate mining profitability. If you want to speculate on the price, just buy directly on an exchange. It's a bit misleading to only show coins that have appreciated in value. It's odd the article doesn't mention the different mining algorithms. It's definitely not profitable to CPU or GPU mine any SHA256 coins, given ASICs are ~10,000 times more power efficient. Yet he suggests CPU and GPU mining, then says he's considering buying Antminers?
