I went through some of your post history to see if you are registered on some exchange aggregators including bestchange. Among others
https://bestexchangers.ru/ru/detail.html?xobmen=718
https://rates.guru/en/exchanger/bigbank-top/reviews.html
all returned the same inactive status and no meaningful reviews to draw from. I then went further and found the "mmgp" forum, you stopped posting updates between April 2019 and May 2022 (it's the same as this forum). Do those gaps count as testing years (seriously is this service still run by the same people)? I noticed you changed your domain extension a few times and it's honestly confusing.

You don't know Bestchange? 
I think he's talking about a global perspective. Best change is more well known on this forum. But there are a few similar platforms especially those based in Russia.
