you can see in screenshoot
or video in work your bot
i think is client want see your perfromance in your bot before buy
Even if OP is posting a screenshot or video, it will not make people want to buy the script. Screenshot or video is easy to be faked, we can make very nice screenshot/video to tell other people "hey, this script is great to make money. Look at the video as a proof and you can buy the script only $10". This will not work, I believe people are not too dumb to believe what they see on video on screenshot.
