What is CoinsRW?

Excuse me, could you please elaborate on what CoinsRW is exactly? I've come across it a few times in the cryptocurrency space, but I'm still unclear about its specific purpose and functions. Is it a platform for trading cryptocurrencies, a wallet service, or something else entirely? Could you provide a concise yet comprehensive description of CoinsRW, including any notable features or services it offers? Thank you in advance for your clarification.
