Giving gifts during the live streaming session is now the norm of the modern world. On YouTube viewers can now buy Jewels which are then used to buy virtual gifts to the stream they are watching.
Streamers can then convert these gifts into income money that is also given the name Rubies. Each Rubies is worth 1 cent. At this time this feature of giving jewels is only activated for creators in the YouTube Partner Program in the United States only.
This feature is seen as a way to attract creators to live stream regularly on YouTube to generate revenue. It can also only be used if the streaming is done vertically.
This can be seen as another feature that takes inspiration from TikTok which popularized vertical video streaming with prizes that can be given to streamers by viewers.
