-- @usage
-- nmap -p 8333 --script bitcoin-info <ip>
--#this is the command you need to use inside a terminal or consolei believe this would work on also but id say better results all round with a modded version of nmap using lynux system. This project is only a fraction done but works with what iv layed out. as weeks go on ill carry on working on this and modding it up to the goal i expect to achieve im Crypto0sy its 2021 and im right on a mission building some Dark Dark tools for the use with bitcoins and crypto currency. Date now is Saturday/18th 2021 and iv just passed this file out to a very close friend i believe as well as work copllegue within  the WWW.
