Could you elaborate on this? I get the maintenance part, but more efficient mining? how so?
All I'm saying is, do not diversify your ASIC miners, focus on one algorithm.
That way, you'll get a
higher hashrate to get more of that particular coin than buying different ASICs to mine other coins which could lead to loss that will be deducted to the total profit of all of your miners.
You only have to research intensively on the coin/algorithm of your choice.
If you want to diversify your assets, use the profits or part of the remaining funds to buy them (
not so different with buying them using the initial funds but you got the hardware for your "investors" to see).
This all because you're already at the halfway or quarter of your plan.
If you can cancel all of it and do the usual
buy-n-hodl, that's a good decision too; as I said in the first reply: It's up to you.
