So the presale starts tomorrow?

October 30, 2017 (15:00, GMT+1, London time)

Looking forward to presale. I checked the project and think it's a good choice for long term hodling. Bank licence is planned for summer 2019, right?

Does it mean that the bank will be completaly operative and working in 2019?

They are planning to start operating long before that, however the banking license itself takes time.

Then can we have our bank account in Forty Seven Bank the next year and use them?

IBANs will be released much faster, yes.
