You were lucky, you got the fund and had cheap electricity cost, even while people say that's mean nothing, but at least you have it. Between buy the coins directly and buy mining stuff, both have their own risk. You were doing the right thing with splitting the fund (Don't Put All your Eggs in One Basket). As above said, you need to concern on capital recovery as your priority.
 

Then about the mining tools that on your plan, I have no idea about it, since my last ASICs was on the museum four years ago. 


But, if you are talking about GPUs, I on it currently.
I'm also a GPUs miner (home miner), my electricity cost is three times of yours. My daily profit, opps..seems like will be better to say, my average monthly profits are 200% of the electricity + operational cost (not bad  ). So, when I need to pay the electricity+operational cost for $1, I still keep $2 as my profits (nowadays). I can add some SC of my current mining process, but that's not good for me.
