I'll say this
yet again - since people in general seem to like making things up and then claiming them as fact.
Firstly, the KanoPool has never even been as high 4% of the network.
Next, though not really related, I have stated many times that I'd never let it get over 10%.
Though I'll also throw in, that most people on the pool know, I'll also lower the fee to 0.6% if the pool ever gets over 400PH
Anyway, the ups and downs of the pool hash rate are various, but the hash rate running down since Nov 2018 is quite straight forward to explain and, again, I've explained it before on multiple occasions.
I guess the problem is that people prefer to make up reasons and pretend they are fact, rather than ask.
The largest miner on the pool, that had been on KanoPool for a year, that was something like 75% of the hash rate, moved to ViaBTC due to a low month luck in Nov 2018.
He IPO'd his company that year, and the board of directors couldn't understand or handle variance
Yet for that year, including that bad month of luck, the pool was still ahead of the top pools in PAPPS%
It was simply a 'quarter' issue - companies get upset when one quarter is bad - even if the other quarters make up for it.
It's quite obvious on the "Monthly Statistics" table - Nov 2018 200+PH - then Dec 2018 50+PH
The hash rate after that had someone throwing a % of their pool at KanoPool every so often, but that source of hashrate ... got shutdown.
Thus like
EVERY other small pool that's been around for a while, the low hash rate has scared away miners.
3 of the many offers I've had for a large miner to join the pool, that I rejected were:
1) I guess he quoted his hash rate to get me interested, but ended up saying he only wanted me to do cgminer changes - so no use for the pool.
2) Wanted ownership of part of the pool - sorry not going to do that since it's effectively just giving someone free mining
3) One group, who only did management of the mining for someone, but didn't own it, said they wanted kick backs and that ViaBTC gave them kick backs so I should also. Not sure where these kick backs were supposed to come from since the pool fee here was way lower than they were paying there
As mentioned previously, I've also had 2 people discuss joining (900PH and 200PH) but couldn't get their board to agree - so alas didn't happen.
Thus I really don't have issue with how I've been running the pool.
1PH is only 10-20 miners these days, so you need to be talking a couple hundred PH before you are referring to a 'large' miner.
