the top number randomly generates numbers as fast as it can if you get lucky, that number is in the list of numbers found inside, in which case, you generate 0.1 block/crypto, the bottom number. this basically simulates crypto generation, as it gets harder to generate crypto over time. sell your crypto for cash money by pressing space. this gives you (crypto x sell price) money. the sell price randomly fluctuates, so get those good deals!!! you can invest in crypto by pressing i gain as much money as possible i guess
