i read a rule in regards to mining/cloud mining , thats was before when im still active on this business . they say that the more you run the mining software or the mining tool , site ( whatever it is ) the more the coins you will get . that sounds that its not against thier rules  .

adding multiple widget on a single website ? will that make the site occupied by widget and makes the site less attractive , its like you put so much annoying ads but putting one widget on multiple site is a more better approach .
