Might be worthy to read up
https://bitcointalk.org/index.php?topic=1585408.0 but i dont know if these is updated or already a dead thread since i do see on to their list with Betking which
do really have some problems or issues as of this moment.
The thread you linked is locked and during those times Betking had a good reputation that's why they were getting a lot of success. If we dig through coingambling's post history his last investment thread was
this one. With betking's current state I don't recommend investing any Bitcoins on them because of their high commission (50% on investor's profit) and according to
Dicesites they're the lowest dice site in terms of overall wagers.
