This can't occur because users choose their own round.
Can I verify everything you've presented in this thread in Wasabi client? I'm curious. For example, I had used Wasabi when reviewing it, and I don't remember it allowed me to choose my own round.
I'm sorry if you can't get the context of the simple point I'm making. But a coordinator won't miraculously have millions in liquidity simply because it went online.
No matter how many times he repeats it, running a coordinator in the right way, isn't simple to do. To have coinjoin participants, you need liquidity, otherwise you're not attractive. It's like being a maker in Joinmarket, but takers need to manually type your URI.
