When you invest your money through Scripbox, it goes into mutual funds and when you withdraw it comes directly back into your bank account. It never goes into our bank account.
The mutual funds are held in your name and all the details are available to you. So in case something happens to Scripbox, you can deal directly with the mutual fund company. It may not be as easy as doing it via Scripbox but your investments are completely safe.
In any case, Scripbox is a well funded growing business and this is a hypothetical question.
