hi
Is AdBTC scame?
It seems that were 2 reports about
"Many times I have requested a withdrawal and your proved confirm email link is Invalid withdrawal link!"
if a website displays errors about/when withdraw then means it's avoiding to pay honestly/constantly. If you cant withdraw your work send them a ticket support and if the issue is not fixed i suggest you to leave the website .
Every day about 5 bitcoin websites are launched and 3 or 4 from 5 turns out to be scams to fast or were created on purpose to be scams.
