I have a theory on the reason for downtime with nucleus. Maybe ya'll have noticed the addition of a second captcha field during 2-FA? I have noticed previously that notifications are visible prior to authenticating your PGP by decrypting for that key phrase. I have a feeling that some vendors, maybe even buyers, found a way to access accounts with only a password, circumventing 2-FA completely. That would explain the weird coin movement some vendors talked about, right? The notifications are no longer visible at the 2-FA page. The 2nd captcha after password makes me think that people were brute forcing PWs. Who knows tho, i am hella high right now.
I like the way you think!
