Hello, not new to the bitcoin business aspect, expanding my horizons. i deal in all kind of mining tools for Bitcoin but the S-series antminers very are efficient for any Bitcoin Miner.

S7
The S7 is powered by a 28nm BM1385 ASIC chip. Kept cool by dual fans (or a single fan in the case of a particular batch), 135 of these chips are spread across 3 boards. The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners.
PROS

S9
A vital enhancement upon the 28 nm design usual to other modern mining devices is the 16 nm fabrication process used in the manufacture of the S9, existing power supplies, at least those of sufficient wattage, are fully compatible with the S9.
As per the inputs discussed above, the S9 will yield 0.285 BTC / $159 per month and 3.36 BTC / $1939 in a year.
What makes the S9 the most electrically-efficient mining device to date is the cutting-edge manufacturing process.
