I tend to agree with 1 BTC = 1 BTC.
I am always surprised when I hear people say this. I don't really think they believe it themselves, or they might think that way when it benefits them. If you think 1 BTC = 1 BTC, and it will always be 1 BTC, then the same logic should be used in situations that don't benefit you.
Let's make it easy and say that at one time in the past, you had to pay 1 BTC for a USB drive. We are going back to a time when 1 BTC = 1 USB drive.
Now fast forward to the present. You are saying that 1 BTC = 1 BTC (1 USB). Are you telling me that you are ready to pay a USB drive 1 BTC in 2021 because nothing has changed and 1 BTC will always be 1 BTC? If that is the case, I can make you a great deal and give you 50% off for each USB drive you buy from. So you are getting each USB drive for just 0.5 BTC! Imagine the profits you would make with this.
Let me know when you want to start.

That is why 1 bitcoin isn't always 1 bitcoin.
Having said all that, I hope the ChipMixer participants keep receiving the same weekly BTC rates if CM feels that is the way to go.
I am not even sure why the discussion about CM rates even started. Doesn't seem right to discuss it and give suggestions on how to lower payrates, and if and when that is going to happen.
