What? Account grades for what?
I have never heard of such a thing where I'm living.
Sure, I hear that your account can get frozen if the bank thinks you are receiving way more money than they think you can afford or something along that lines - to prevent money laundering - and all that can go away by giving them a certified source of funds document. But what you are describing sounds crazy to me.
We should all be thankful that Bitcoin doesn't come with this kind of BS.
I see OP’s post been looking crazy I think it’s a country thing because what OP has actually written is definitely the truth which I have had to face from my local bank in the past. The problem is mostly on an account which you open without providing government owned documents like the national Identity Card, they simply set a very low limit of capacity that the account can hold, very little amount it can also withdraw or transfer per day. I will say it is simply just like the CEX with KYC protocols they simply give you limited access to your account and if you don’t provide full KYC and receives large amount of money they don’t bounce it back but withheld until the KYC is passed. It’s not strange but thanks bitcoin though.
I didn't write this in my reply above but I know that is goes without saying that P2P trades are just seen by the banks as random transfers from one person's account to another, and comes with extra risk especially if they are transfers between international banks.
Yes it’s simply two individuals just sending each other money and nothing more, that’s why in countries where cryptocurrency trading is illegal they resort to P2P because banks cannot identify where the money is from. They only way they cam know is probably the sender has registered his account with crypto tag or maybe the transaction has a crypto word as narration, and the amount is huge
