The Zap feature is not just about simple financial exchange. Even by sending just 1 satoshi as a Zap today, it can create additional emotional joy for the recipient for various reasons, such as being impressed, wanting to share, feeling happy, and so on. Zaps can serve as a means of emotional interaction between people. The amount itself, whether large or small, is not important. Just giving 1 satoshi as a Zap can bring happiness to someone as a gift.
