The most famous Bitcoin address is Genesis Block address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa and the second is 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF , as far as I know this second address private key belongs to Mtgox's hacker and FBI had arrested Russians hackers, are those hackers the private key holders from 1FeexV?
Here comes the main question, this address starts with 1Fee, that may suggest that is some kind of fee charged to hackers move or whatever cognitive matter, so based on this prefix 1Fee, is it a vanitygen address?
