With top goan government officials like mandrekar, caro, nayak, pritesh chodankar openly involved in banking, financial fraud, making fake claims about bank account ownership, many people especially small business owners in goa have very less faith in the banking system, and do not keep much money in the bank.
Many people appear to be investing their money in gold and jewellery

So many jewellers from all over India are holding their jewelry exhibitions in goa regularly because it appears that they are getting a good response from locals interested in purchasing gold.
The locals may not be interested in purchasing from established jewelry stores in goa, because the purchase is more likely to be reported to local government agencies.

Most of these exhibitions are held in posh hotels in panaji, margao
Compared to Mumbai, where almost no jewelry exhibitions are held, far more exhibitions are held in goa
