@realtrade77 - BTSC does Bitcoin mining (transaction verification services), using 15 of Antminer S7 machines having a total "hash rate" of 70 terahash/second.
For comparison, "Slush Pool" Bitcoin mining pool runs at around 1,200,000 terahash/second. At that rate, they earn about 10 Bitcoin every hour. That's $160,000/hour which they divide among 50,000 members (people who link their own hardware to the pool and contribute mining capacity). So, BTSC can expect it's hardware to produce 10 Bitcoin roughly once every 18000 hours - about $160,000 (today's prices, and ignoring operating costs..) for holders of its half-billion shares, once every three years.
Another comparison: MGTI (46 million shares, $3.85/sh) is building (est. completion by March '18) a 70,000 terahash mining facility which should collect 15 Bitcoin roughly every day. Also, Santo Mining (SANP, 422M shares, $0.0002/sh) is building a 1,300 terahash mining operation (20 times more than BTSC) which should bring in $160,000 (at current prices) of Bitcoin every 90 days.
Projecting earnings from reported, intended future installations of mining hardware is somewhat risky. I offset that risk with the assumption of zero increase in Bitcoin price. Still, I see MGTI as a 1000x better investment, and SANP as a 40,000x better investment than BTSC for a given dollar investment.
So... BTSC does almost nothing, even compared to the "50 shares for a penny" SANP. Mostly, what BTSC does is sell stock to people who aren't looking past the "Bitcoin" in their name.
