How do you think of investing in BTC mining?

the difficulties to find a stable site and power is too large for people who wanna get into the mining industry, just can find some reliable company to provide one-stop service like , the price of m60 176t i got is 2992+599=3591usd/unit, and the power cost is 0.058kwh. but as current btc price, the payback period is around 2 years, so i just wanna hold btc and wait for bull market.
