This won’t help surviving the upcoming next halving of the PoW block reward!
The mining industry might take that into consideration when purchasing new hardware. But the operation of the miners creates ongoing costs for power consumption (and cooling?) that need to be covered by the mining income.
The mining will be in an equilibrium between operation/investment and income by mining.
If there’s no steep rise of Bitcoin price after the PoW reward halving, a lot of miners will be shut down or aimed at other SHA256 mining processes (say hello to Peercoin PoW rewards of below 30 PPC per block
).
And as the diff adjustment takes 2016 blocks this can lead to awkward situations for the Bitcoin network.
I fear for Bitcoin!
…the last Pow reward halving at Bitcoin occurred at a time when no such mining industry was in place. The next halving will be different!
To play with some numbers:
current BTC hash rate is approx. 300 PH/s (=300,000 TH/s)
current PPC hash rate is approx 300 TH/s.
If only 10% of the BTC hash rate would be aimed at PPC after the BTC PoW block reward halving, this would put another 30,000 TH/s to the PPC PoW process.
Taking into regard that if the difficulty goes 2^n, the derived coinbase reward is 2^(-n/4).
With a roughly hundredfold of the hash rate, n is approximately 6.64. So the resulting coinbase reward is 2^(-6.64/4)=0.316.
So compared to the current coinbase reward of ~78 PPC the resulting coinbase reward would less than one third of that, below 26 PPC.
Why am I writing this PPC calculation in the nubits forum? Because some of the readers here might be interested in that 
…if half of the 300 PH would be aimed at PPC’s PoW process, this would reduce the PPC PoW coinbase reward to less than 13 PPC…
