What's the best approach to start SIP?

I want to invest some money every month. What’s the best way to do it using zerodha’s add on products.

  1. SmallCase
  2. Coin
  3. Direct ETFs

If its same amount every month, then I’d say Coin.

  1. Smallcase Is better than MF and etf but it requires little more amount 10 to 30 k minimum.

For amount around 5k you can go TO ELSS MF if your purpose is of tax savings otherwise you can go to etf.

It has low cost versions also.
