It is simply impossible for these scammers to have any kind of access to such large amounts of bitcoin ($468 million) that have never been moved for a decade, and yet need $56 investments!
I think what OP is saying is he bought $56 worth of bitcoin back in 2010, and these are the addresses he received it to, which he has since lost access to.
Look at the date the $56 was added and the dates of the dividend still paid each period of the fiscal year over the years
The incoming transactions you are seeing on those addresses are dust attacks and advertising spam. They not dividends being paid.
I paid by clicking on the ad from bux.to. Now the site is closed
Bux.to was a scam:
