Bad example.
M7M is a regular POW algorithm, there's nothing mobile about it, It can be mined with any desktop, laptop, workstation or server CPU.
If anyone claims M7M is mobile only they are scammers. My previous statement stands, all mobile only mining is a scam.
Did you get to read the whitepaper?
Did you read my code?
Seriously, keep in mind Magi is 10 years old and so is its white paper and the M7M algorithm. The white paper, like many in crypto, reads more like a
sales pitch than a technical description.
Block reward adjsustment is nothing new but is a property of the coin, not the algo, and it applies to the entire network, not individual miners.
If Magi worked as you suggest it would destroy pool mining because a pool appears as one miner to the blockchain and would therefore be
penalized as a whale.
Also keep in mind hashrate is an artificial metric, it's calculatred based on submitted shares or blocks over time. The blockchain network only sees the submitted
blocks, it can't tell how they are produced, whether it was one big CPU, a pool of small CPUs, or simple luck.
The fact is mining on a phone is done with the CPU, and competes with any other CPU, big or small.
Conversely any POW coin that can be mined on a desktop can also be mined on a phone if the software is available. Real POW mining on a phone should be avoided for
reasons that I have articulated elsewhere.
"Phone only POW" is just a marketing lie.
Edit: the only thing unique about M7M is the use of multi-precision arithmetic which makes it unsuitable for implementing on GPUs.
