Bank Recommendation & Crypto

Any Banker/Knowledgeable person here?

1. Which Bank is best for discounts on food & stuff?

2. I've few million PKR to start business, given by my family.

Will transferring this money to new account create any issue? Because I didn't earn it.

1. I did small Binance P2P transactions few years ago.

Should I transfer money to new account by taking out cash to avoid link, or is it safe to transfer directly from app?
