Well, technically I can steal people. You should use two-factor authentication and keep your items in a safe account if you do not trust our service. Keep in mind that once I hack one user, all others will just go away, so probably not a good idea for me.
You can't use your own VM and it wouldn't be worth it.
The bot is sort of expensive, but, if I am not mistaken, tibia 12 consumes a lot more resources. Here in my notebook, one single tibia client uses 80% cpu already. Bot uses another 80%, so it is necessary at least a 2x CPU to run a single client + bot, which costs already 10 USD if you rent a vps. I mean, if I could reduce the price I would. Still you can buy 10 hours for as little as 1 USD. I make around 10kk exp in 10 hours, so 1USD for 10kk XP is pretty reasonable.
