yes (of course) .. It's fascinating how always people love to jump to conspiration theories .. If it were a cyberattack (and so far it isn't proven at all), it would be nothing less than a state sponsored cyber attack to be able to get down the electrical grid from 2 EU countries - and obviously no "reward" such as crypto would be involved behind the scene
Please refrain to call it a conspiracy when it is a valid hypothesis with valid facts.
It is common to use Monero as reward for specific groups performing cyberattacks. Please inform yourself on the topics and reflect afterwards on what was written.
