The notorious Runescape Gold website Alch.com have stopped their operation on October 19, 2021. While there is not much information about their shut down reasons yet, it might be related to the newest RWT changes. Here is the official good-bye from Alch OSRS website:
If we'll get more information about the closure of Alch.com, we'll update this blog post.
