The Digit plan is affordable, but what are the main risks or exclusions, such as floods or earthquakes, that it does not cover? I need to understand the details before switching from my old loan insurance.

Before investing in ETFs, I have some questions regarding this:

1. Would a regular ETF purchase plan, like a SIP, be beneficial for testing strategies? If yes, what's the recommended purchase interval—daily, weekly, or monthly?

2. If I purchase ETFs on a daily basis, then how are the transaction costs calculated?
