What are your thoughts and ideas to prevent these scams.
Either do your own due diligence (stick with established, well rated merchants) or use a credit card when shopping somewhere "less than reputable".
Yeah well the purpose of my question is about promoting Bitcoin for merchants.
Thank you anyway for your though
Anybody else ?
your question should be what is promoting bitcoin for "customers" not merchants.
in fact bitcoin is best for merchants! because it doesn't have charge back. the worse thing that keeps happening to merchants is either charge back or credit card fraud and bitcoin eliminates all of these.
but according to your OP it is customers who will be affected by things you said. and if the merchants is trusted and has a good history trusting is not hard.
Yes, you are right, you need to choose a seller who cause trust. Or to agree that you will pay 50 percent of the prepayment, and the rest after receiving the goods
