While the reality of the situation is more complex than this, the overall dynamic should hold up — at least until and unless Bcash
block rewards become more valuable than Bitcoin's.
As
the block reward becomes harder to mine more energy is required to carry out the calculations in this computational arms race.

Alternatively, of course, its
block rewards will have to
become more valuable than Bitcoin's...
When the
block rewards decreases, miners will
become increasingly dependent on transaction fees for their income.
Mining pools exist in general because as mining
became competitive -
block rewards are worth roughly $ 58,000 at press time - individual miners and small mining operations struggled to keep up in the race to win
rewards.
Every 210,000
blocks, the
reward would
become half the previous amount.
If they hesitate to do so, their
block will
become orphaned and they will lose the
reward.
That
reward halves after every time 210,000
blocks are mined, and mining
becomes more difficult as more miners join the network, creating that diminishing scale of return initial coin offerings nowadays try to recreate through their funding schemes.
That incentive is the
block reward — the newly - minted digital coins that a miner receives when they propose a
block to the blockchain that gets accepted and
becomes part of the longest chain.
