VIP Extended adds two main features:
1. The bot control panel/website do you can control/view/manage your bots remotely
2. The ability to use proxies on TriBot, this helps differentiation your accounts and stop chain bans/using flagged IPs or IPs with previous ban on them on new accounts.
Reason 2 (Proxies) the the main reason that people get VIPE.
So if that matters to you, then yes get it!
