no scam.
you can see on their home page
https://coinpot.co/ the amounts that they have paid out over last 7 days.
click on those amounts and you will see a breakdown of all the transactions with links to blockchain to confirm direct wallet payouts.
by my (very rough) calculations, they are paying out around $9-$10k PER DAY! so much for a scam

If they are paying 90 % of what they should it don't mean they are not scammers.
If you steal a single dollar from someone you are a thief , no matter how much you have paid others...And in my option or they scam SOME TIMES or their automated detection system have some problems because people like me did nothing shady / wrong.
And also their support is almost nonexistent because they NEVER answer mails !
So scammers or not they got some big problems anyways.
1) Some sucky auto detection canceling payments to few unfortunate users like me
2) VERY BAD behavior not communicating with users when they have issues !
