We fail to understand that why traders get into dabba trading or such crypto scams as given in the newspaper article. As a thumbrule keep away from crypto currencies and deal only with Sebi Registered Intermediaries.
Please go through the newspaper report and do not commit these mistakes as highlighted in the newspaper report. One fails to understand how a bank official has got trapped in it. Remember that any fraud or a scam will have a greed element and an iota of urgency attached to it and that is the time you have to become mega careful.
