Is a WhatsApp message from an unknown number saying 'hello dear' a scam?
Almost always yes. This is the opening move of a romance scam, task scam, or investment fraud.

Explanation
Scammers send mass WhatsApp messages to numbers they either purchase or generate randomly, using a friendly greeting such as 'hello dear', 'hi there, do I know you?' or 'sorry, wrong number — but can we still chat?' The goal is to start a conversation. Once engaged, the conversation moves toward romance, friendship, and eventually a request for money or an invitation to join a 'very profitable' investment platform. The friendly small talk can last weeks or months before the scam reveals itself. If you do not recognise the number and there is no credible reason for the message, do not engage.
Those opening messages are sent by the tens of thousands, often from industrial-scale operations, and a reply — any reply — is the only 'qualification' the sender needs. Even a polite 'wrong number' confirms your line is live and attended, moving you onto lists for further contact. The scripts that follow are patient by design: days of small talk, shared photos, and apparent friendship before finances ever surface.
Deleting and blocking without responding is the complete defence, and reporting the number helps the platform disrupt the operation. If a conversation has already progressed, judge it by the trajectory rather than the tone — an accidental contact who stays, deepens the friendship, and eventually mentions investing is following a script, however warm it feels.

Frequently asked questions
What if they seem genuinely friendly and say it was a mistake?
That is part of the script. The 'wrong number' approach is a deliberate tactic to make you feel you should be polite and engage. Blocking is not rude — it is safe.
I've been chatting for weeks and they seem completely genuine — now what?
Apply verification before anything financial ever comes up: a live video call, consistency checks on their story, and absolute refusal of any investment or money topic. If the relationship cools the moment you verify rather than comply, you have your answer.
