Hello!

Can't answer this question, it's MinexBank algorithms.

I don't understand why you don't understand that it isn't neccesary.
I mean what is the big deal, nobody can steal anyones coins. The only thing a hacker could do is:
A) park your coins for you (nice for you, less work)
B) cancel your parking, in which case you find out soon enough and you can just transfer the coins to another address and create a new minexbank account.
C) change your password, in which case you just transfer your coins to a new address and create a new minexbank account.

Either ways it's no big deal.

Of course 2FA is a strengthened strategy for account protection, there's no point in discussing that. Facebook gives you the possibility to use it. My banks (I have 3 different ones) all propose 2FA too as an option if I want to. Google, Steam, Apple and so many other companies offer it as an option.
2FA is seen, most of the time as a boring thing by users until they get robbed or hacked.
2FA might not be incredibly necessary for minexbank but at least, they should give the option to activate it if you want. There are some people concerned about security and this is company's duty to try to fulfill customers needs/hopes.

My investment is much higer that 10.000$ But, my PC is protected, wallet is encrypted+backup is saved outside from PC. I have long and strong password at Minexbank. But in bank working people who knows about security much more than you or me. And if they are saying 2FA is useless anymore, so that is like that. And nobody say you why, I hope you understand why?

I'm tired of that discution. Just read that. https://sakurity.com/blog/2015/07/18/2fa.html  just in few words. If i'll huck your email, I can get access to everything what you are encrypted by 2FA.

I never said they could steal your money, I said they could make you loose a potential reward by cancelling your parking. It's different.

If you are afraid of potential loosings what are you doing in crypto at all?

Hi guys , i am just wondering should i live my wallet open while i am using the minexbank or can i close the wallet some time?

Yes. Because MinexBank is different from Proof of Stake, it is possible.
