I don't mine of any of the larger pools I do not think they play by the rules and I do fear they short change miners out of there earnings.
I myself mined for 2 years solo.. yes 2 years. without a single block to be found.
I now mine here at kano I have very low power only 2.5th online with a further 2.5 awaiting to come online next few days.
I know that cpu was no longer viable dew to demand on cpu and difficulty and no pools accept GPU or CPU anymore so technically they are obsolete in the BTC game..
Satoshi told us in his whitepaper that an attacker on the chain would find it more profitable to play by the rules.. But my understanding of this would be that would be find on one chain.. But we have two chains now so any attempt to "attack" bitcoin for personal gain would now benefit the attacker as they can mine a separate chain and still earn.
he also stated
We consider the scenario of an attacker trying to generate an alternate chain faster than the honest
chain.
"Block height. BCH is currently ahead by 8143 blocks."
https://fork.lol/blocks/height The race between the honest chain and an attacker chain can be characterized as a Binomial
Random Walk. The success event is the honest chain being extended by one block, increasing its
lead by +1, and the failure event is the attacker's chain being extended by one block, reducing the
gap by -1.
The probability of an attacker catching up from a given deficit is analogous to a Gambler's
Ruin problem.
The above statement is true if both chains are of the same specification.
But this did not take into factor a new chain with "emergency" DIFF adjustment being used to create a longer chain?
If I am mistaken correct me on this.
He also stated in the whitepaper
The probability drops exponentially as the number of blocks the
attacker has to catch up with increases. With the odds against him, if he doesn't make a lucky
lunge forward early on, his chances become vanishingly small as he falls further behind.
Now... what better way to get a foothold than to pump the Bitcoin DIFF so while on the other hand having a much lower DIFF on 2nd chain and being ahead of BTC chain by a fair bit..
