Just noticed this in backoffice Q
"* Effective 25 April 2018, winning the 60-day challenge will not entail brokerage refunds. Digital winner certificates will continue to be issued. "
Seriously zerodha?? It is okay if you stop brokerage refund but isn't it unethical to stop it suddenly without any notification? You could have said that no brokerage would be refunded from new challenges onward but existing challenges will be refunded or something like that.
