IT will go back to paid it's just a glitch.
You're right. It's already back to Valid and Paying.. Hope that it will be changed to Paid soon. Today it's 9th day from day when I sent money...
Check your order details and make sure you paid the correct amount. "Paying" means Bitmain received only a partial payment or for some other reason they think you didn't pay in full.
I paid full amount. I am 100% sure. Have opened ticket fot the same, so let's see. Still waiting for their response.
