one of the main idea behind crypto is decentralization . and if one company or even two control the mining , then that basic principle is destroyed
what i like about monero is that it can be mined using GPU , CPU . so AMD and Nividia cant control it .
i will quit buying or trading on Monero if they went to ASIC .
How do 1 or 2 companies own mining exactly? Using your argument you could say that Nvidia and AMD control all of GPU mining. Producing products to mine does not equal centralization.
