Could you elaborate on why you are questioning the credibility of a handshake? In the traditional sense, a handshake has long been a symbol of trust, agreement, and respect between individuals. It's a nonverbal gesture that communicates a willingness to work together and build a relationship. However, in the context of cryptocurrency and finance, where trust is often a major concern, is a simple handshake still enough to ensure credibility? Or do we need more robust measures in place to verify the trustworthiness of parties involved in transactions? I'd love to hear your thoughts on this.
