Mining is hardly profitable that's one, two, we are approaching the cycle top (don't ask me how I know, we have been doing the same cycle shit since forever), terrible timing to invest money in mining gears, the next cycle is going to be even more brutal.
My strategy is exist the market slowly (December is probably going to mark the cycle top with 1-2 earlier or later) then a long bear market, start my accumulation, wait for the next cycle.
