from coinwartz: if you buy antminer s19xp you pay 17999.- usd and you make 1.96 usd per day minus pool fees at an electricity charge of 10 cents per kwh which is very low
this shows that bitcoin mining is not profitable for a normal miner.
it can only be made profitable for large corporations buying asics in bulk, operating large mining centers, as big as amazon warehouses or google datacenters. as a result bitcoin mining is becoming more and more centralized.
monero can be mined on any pc, telephone, even on android car stereos. it cannot be mined on asics efficiently in order to keep it decentralized
