I was curious how many colluding mining pools it would currently take to 51% attack some of the most popular PoW coins:
Bitcoin: 3
Monero: 3
Litecoin: 2
Dogecoin: 2
BitcoinCash: 2
BitcoinSV: 2
Dash: 2
EthereumClassic: 1
Zcash: 1
Ironically (and interestingly) Qubic may have further distributed Moneros hashrate and broken up the dominance of the previous three major mining pools
