im wonderin if you really make profit ?
i mean the price you pay the antminer + electricity cost + increased difficulty each month (well dont know how often)
so is it really worth investment, even for s9 ?
not to mention if you have some maintenance and if you need to repair/change parts ..
i really want to start mining but not sure if it worth money anymore.
It's pretty hard to be competitive. Some big pools use miners they develop themselves and they delay their release to the public.
0.06$/kWh CAD is pretty much my breaking point for current gen miners and that's if you already own the miners.
Import taxes and shipping costs are usually a deal breaker.
