Well looks like you didn't become the top after all and sold out to p00in
They advertise themselves as "the top mining pool in North America" or at least that was their mission, I am pretty sure most of their clients joined them for that exact reason, another portion must have joined them because they are Non-Chinese which was a bit of a counter measurement against Chinese mining pools, and the irony is that they had to capitulate to the largest mining pool which so happened to be Chinese.
(though no pool except mine seems to do this analysis anyway)
It seems like nowadays all you need is a ton of
BTC to own a large mining pool, Binance is a newbie in the mining industry, with less than a year around they managed to secure 10% of the total hashrate, it doesn't seem like the perfect code and analysis matter anymore, just own enough bitcoin to offer 1-2 months of free PPS+ payment and you end up with 16EH worth of hashrate.
