Exchanger monitor
A service that collects rates, reserves and ratings of many exchange offices and shows them in one place, so you don't have to check each site manually. Example — BestChange.
In more detail
A monitor does not perform the exchange itself — it is an aggregator: it collects offers from dozens of exchangers for your direction and sorts them by how favourable they are. This saves time (no need to check sites manually) and money (the rate difference is visible), while ratings and reviews act as a first filter against scammers. You still make the actual deal on the chosen exchanger's site.
