I have slice SB account by NESFB with considerable money (according to my portfolio, ymmv). But, not all the money. I don't put all the eggs on the same basket. Diversification is very important.
I don't live in NE or in Banglore to have a nearby branch. In finance, every penny comes with a risk factor. For example, stock market investments are bit too risky than FD. Gold is risky if we can't keep it in a safe custody. Cash is risky in a different manner.
Usually, keeping money in a bank without a nearby branch is risky. That's why I still haven't opened an SB account with Kotak. However, I took a different stance with slice (technically NESFB) and took the risk to open an SB account. If I had to visit a branch in slice, most others would have to do the same. So, I expect that in slice/NESFB, all things would be done online going forward (like re-kyc after a few years).
Please choose wisely. Please do not trust me or any online review.
