Your post doesn't really make sense. Samsung gets involved in this market because of how much potential there is. If we look at how much demand there is for proper mining gear, and that on a very large scale, it's more than lucrative for Samsung to enter this market. If they manage to offer their miners for a lower sale price, they'll probably start messing with Bitmain's market big time. Don't think anyone here will lose sleep over Bitmain losing its iron grip on this element of the industry. More entities being able to buy cheaper mining gear means a much stronger network in the long run, which of course will drive up the difficulty even further, but that's not a problem. Increasing difficulty means increasing demand, and if the price keeps growing as well, then everyone remains happy.
