As far as we know, Bestchange does not charge anything to the exchangers, but takes part of the profit through the affiliate program. They cannot have much influence on the business policy of exchangers, and the most they can do is exclude someone from monitoring (as they did with go-go).
This exchanger can also be found on Google, so I'm sure that no one will accuse Google of being an organized scam and charging scammers something.
You may not have all the facts. In February 2025, the Bestchange service was blocked in Russia at the initiative of the Central Bank due to numerous violations.
The block was mainly related to new laws restricting the advertisement of cryptocurrencies, which shows they are seen as active promoters, not just a passive list. Reports also mentioned that the block was due to their failure to properly monitor exchange services, leading to issues with fraudulent exchangers and the hiding of negative reviews.
As for the 'affiliate rewards,' that's not the full picture either. Bestchange's revenue is directly tied to the transactions they facilitate, making them a financially interested party in every exchange
