I own a certain amount of cryptocurrency and I buy new currencies very rarely.

I am not a trader and therefore I have not registered on real exchanges. ~Anonymous instant exchangers were enough for me.

And a few days ago I went to ChangeNow.io and sent them 100 BCH. They had to send me 11 bitcoins. (You may think it is crazy.... Maybe yes.)

But time passes and I see a message that my transaction seems suspicious and they demand to provide documents and information about funds origin.

I began to write to them that I was not going to send them anything and demanded that they simply return 100 BCH back. They refused me and continued to demand documents and information about the origin of the funds.

I got tired of all this and took the first picture from google.images (with someone's passport). Why did I do this? Because I did not take this bucket shop seriously. This is not a company - they have no address, no phone, they do not even have a real company name. I'm sure it's just a few people working from home. I did not want to say anything about myself, because I did not break anything. But I still explained about the purity of my BCH and it was perfectly visible from the very beginning:
1. There is only one incoming transaction(a few months ago) and one outgoing transaction(to ChangeNow.io) on the wallet.
2. The origin of funds on this wallet is another my wallet (this wallet was created 5 years ago(before bitcoin hardfork) and it was replenished only once(5 years ago))

That is, I have owned this funds for 5 years. This funds are absolutely clean. They agreed with this but then they demanded to make a selfie with my passport and piece of paper (ChangeNow + Date). I began to argue with them, demanding to return BCH back, because they are clean and they themselves know it.

As a result, I had no choice but to make a photo of real passport and make a selfie with a passport and a piece of paper. I sent it to them and said that the previous photo was sent accidentally due to ignorance and misunderstanding of the seriousness of the situation.

Now they say that due to the fact that I deceived them they will now check my photos with regulating authorities.

Do you understand all this madness? They know perfectly well that I am the owner of absolutely clean BCH and they do not return them back. I do not demand them to make an exchange. I just demand to return this BCH back to the legal wallet.

This is not their property. Why do they hold them? I gave them everything and they now tell me that they will check my documents through regulating authorities (indefinitely - no time limits, no guarantees, nothing).

Who are they to hold my property? They are thieves. And I repeat, this is not a bank, and it's not a real exchange like Binance or CoinBase, which is responsible for his work and controlled by the state. These guys - are nobody and nobody knows who are they and it is absolutely unclear for what purpose they find out the identity of the owner of such a large amount of cryptocurrency.

I will provide proof of this to any moderator (if necessary)
