To see WHOIS from a website, we can go to http://whois.domaintools.com
WHOIS can be use in analyzing how long a HYIP company can survive.
This is a sample WHOIS of two HYIP company
Company 1 :
Company 2:
From WHOIS data, we can get conclusion that company 2 have bigger probability of longer lifetime than company 1. That caused by company 2 must be spend more money to buy longer domain name than company 1.
