I've only recently heard about this. So it's not a bank account, but some savings plan where you can deposit and withdraw money as if it were a bank account. What are the restrictions here? It also seems that "returns are no guaranteed". What does that even mean? Interest isn't guaranteed? Anyone able to advise?
The main restriction is that deposits and withdrawals aren't instant. Right now, deposits take around 24hrs. Withdrawals take around 30mins to 4hrs. However, this can change. Their T&Cs notably do not include any solid timelines where they
MUST give you your moolah within a certain set timing from you indicating your intent to withdraw.
Returns not guaranteed isn't something to be worried about. It just means that the interest given will be 2.5%, until it isn't. This is the same as how any bank high interest savings account operate. They give you a high interest, until they don't. The interest isn't locked in, and is subject to change as the financial institution sees fit.
