What exactly is min-address? how do i know what is my min address?
Your answer can be found here:
http://www.minaddress.info/#faqAs for how to find out what your min-address is, just enter your normal BTC address in the field at the top and the website will do the rest for you. Basically the first part is the first block that your address appeared in and the second part is the first few characters of your normal BTC address.
