Up to you

but I honestly don't understand why someone would prefer to just give away 500k rather than just lodge 800k into your own bank account which you keep.
Also bear in mind that you only NEED the 800k in the bank in the first place if you have ZERO income. If you have pension income you can offset that against the capital requirement. If you can show 65k monthly pension income you need nothing in the bank. If you can show 33k pension income you only need 400k in the bank, and so on.
Additionally the 500k only gets you five years, if 500k got you 20 years for sure I could see the security point but I don't see how if you are comparing to the five year visa there is this great increase in security of tenure either.
