To add, can anyone confirm if you need to have csno tokens in a private wallet before you can get dividends or can you put them on the site and get them too?
As far as i know (and read at some point) you must have it in your ETH wallet,which must be compatible with ERC20 tokens. Like myetherwallet or metamask.
Yes that's correct, alex had given instruction on how to receive the dividends. it can be found on bitdice medium blog.
I really dought that any exchanger can (or will) give you the dividents if you keep your tokens there.
They probably don't want to do extra work/deal with it. if anyone had kept CSNO on exchanges their dividends will be taken up by exchanges. tokens that distribute dividends are best kept in private ETH wallet/address.
