Support YouTube creators by paying for a 'Super Chat'

Let your favorite YouTube creators know how you appreciate them by paying for a Super Chat
Currently, a small number of creators have Super Chat available such as iHasCupquake, Great Library (buzzbean11) and Alex Wassabi. On January 31st, that number will increase as creators in 20 countries and viewers in 40 countries will support the new feature.
To make your Super Chat stand out, it will be highlighted in different colors depending on how much is spent. A countdown timer will keep track of the time remaining, and a Super Chat can be taken down before time expires. The feature is available for Android users now, with iOS support coming later.
If you want to let YouTube creators know how much you appreciate their work, and help support their efforts, leave them a Super Chat.
