How much time in average does it take for an simple PC to create block?
How much time in average does it take for an simple PC to create block? Let's say I have simple computer (CPU- Intel i7 for example), and I start mining blocks in the bitcoin network. How much time in average does it take to create 1 block? (1 per week? 1 per month? 1 per 3 month? ....) And if the answer is 1 per month or something like that, why not all the world participate in the mining process? it seems like an easy money to earn ... And that's why I think that I missed something in my knowledge Thanks in advance! http://ift.tt/2xQQ7Lk
