Thanks for the post, I just took a good look at this page - clicking the link in the top right to take me here;
https://etherscan.io/token/0x5121e348e897daef1eef23959ab290e5557cf274

you can see a list of a lot of transactions, and, the 'holders' tab also shows the person with 680M - and, this page also states that MAX 29M exist, and this person is shown as owning 2,345% of the total (math = 100% is 100% - I.E. there is a BIG issues with the 'total' coin QTY here also...)

We do still have a group willing to talk to the holder of the 680M of this coin, about a buyout offer - if we can make contact with them, it will be from our main email of; NEWDEVpolyai@outlook.com - please share this info with anyone that may be able to contact this person and the next BIG holder of 157M PolyAI coin.

Thanks again,
