A non profit organization is running a campaign that is encouraging people to sacrifice a small luxury and donate that money to a cause instead. They are building the campaign around Twitter hashtag #IGiveUp.
In general, I've seen "I give up" being used as "cease making an effort; admit defeat. (Google)".
Question: Is #IGiveUp an appropriate hashtag in this context? If not, any suggestions on what would be (Around #IGiveUp)?
