Exactly! i agree with both of you actually, i think after ETH turns to POS miners will go straight to XMR because it's efficient, anonymous, and have a good reputation.
a lot of peoples says that maybe monero price will drop because of that but others say it will rise because the chinese start buying it too! (wich is weird), my thought is in future we will see monero as the 2nd coin on the marketcap value
