There is good for investors if dhan implement the digital gold facility
Welcome to the community!
Thank you for the great suggestion to bring digital gold. Currently, our focus is on enhancing the stock trading and investing experience every day.
All feature and product updates will be revealed here first in the community. 
SGBs are better than Digital gold tax wise and return wise. The only catch is govt may not proceed with new tranche release. However you may try to corner it from the secondary market.
I would also like this, but it seems Brokers are not allowed to offer Digital Gold as a product. Please refer the article below. Maybe Dhan team can confirm.
It’s a grey area. We focus only on bringing the products that come under the purview of SEBI.
