Looking for Bitcoin mining profitability source of information which gives new miners idea about which coin to mine
Much be reliable source
Thanks
You have a LOT of reading to do. This entire section is to mining Bitcoin, not altcoins. And I don't think there really is a sha256 altcoin worth mining over BTC. So pretty much you will mine BTC.
If you really want alt coin's then they do sell some scrypt asics... but a lot of it is dated. So I would do BTC myself, and also check on ROI math before investing, it's becoming a hard game to get into.
