Bitcoin address, so i know that it's generated randomly by clicking on the new address button.
question 1 - does it expire? example, if you give a person an address and years later can the same person send you bitcoin through the same address? or more likely to fail or get sent to other people?
Other stuffs (unrelated to the address)
question 2 - if i have two different computers, can i mine both computers at the same time at the same pool? If i could, how do i receive the coin since the bitcoin wallet in my second computer is totally different from the wallet from my first computer?
Please cure my puzzling mind!!! it's killing me to figure it out!!! thank you!!
