投币

On Bilibili 投币 has taken on a second life as the platform's signature support gesture: viewers can 投币 (give 1-2 'coins') to a video each day, and creators with enough coins gain rewards. The trio 一键三连 ('one-click triple') = 点赞 (like) + 投币 (coin) + 收藏 (save) is a Bilibili ritual.

usage

Original sense (insert coin into a vending machine, arcade, parking meter) is still alive. Context decides whether it's the literal or the Bilibili meaning.
