Hello friends, I am a platinum 4 player at stake.
Today my account was suspended and I was asked to submit proof of funds as I am already verified upto level 3 and proof of funds comes in as level 4
I have asked support and they have confirmed that they do not deem any crypto earnings as legal and valid source of income apart from income made through mining. This means if you are a service provider, a seller or simply a trade you cannot provide proof of funds at stake as they only deem mining earnings as legal and everything else is illegal and invalid.
So if you have money at stake.com and you don't have any of these ready (
https://help.stake.com/en/articles/5328395-acceptable-documents-for-source-of-funds) , please withdraw your money right now.
It is really confusing why stake is disrespecting people who work hard and earn their money from small crypto tasks

I earn my money from trading, and selling some services and sometimes airdrops and stake tells me I am invalid
Well, if they are asking you to clarify the origin of the deposited funds they must have found something suspicious. Always remember that you can have in your possession "Tainted coins" and that can cause red flags to be raised. For instance, if someone sent you some coins to pay you for a service and these coins were coming from a mixer they can possibly raise an alert. Given that the coins you have deposited may have been identified as already being used for illicit purposes, Stake's Compliance team may be compelled to act.
