So there I was, spending all my tu again... and then I thought:
What if there was a savings account at the bank?
No interests, nothing ... just another account where we could store tu. Perhaps there could be an option where we could lock the account, without being able to withdraw tu, for a desired amount of time?
I don't know. Maybe that's a bad idea, but it would be very practical for those who can't seem to be able to save!!
