Need advice about emergency fund

Hey guys, I am looking to save some money for an emergency fund. I recently got a job and right now I can spare about 20k per month. I want to create an emergency fund and I was thinking about putting my money in mahaana.com.

I don't want to keep the money in a bank account as it'll depreciate over time. I am new to investing and would like your guidance.

Is it safe to create an emergency fund in mahaana.com? Are there other better options?
