You're a quick learner and the way you present everything, that's impressive. I got to know this game by reading your post. It seemed like an alien when I read your post. lol... don't understand what's going on and how things work unless I got into it. Thank you very much @achim03 for talking about this game.
By the way, higher-level cards are too expensive compared to what benefits we get from mining. What's your overall experience now?
When you look at the rewards that you can generate with higher cards, I definitely think they are not worth the money. I would start by buying simple tools like a basic showel a standard drill and a standard capacitor. They give pretty good results for the price they cost. In terms of getting NFT's you can definitely improve your drop rate with better tools.
