I really need a clarity in these things ,it is really interesting to see Edgeless etherum smart contract , Etheroll and RouletteToken are sharing their profits with their token holders but what i have to know is how are they going to evaluate those values,do we need to save this tokens in a wallet where we own the private address or will i be eligible even if i keep all of my coins in exchange wallets.
There would not be any point in keeping tokens on exchange wallet, as the tokens on exchange belongs to the wallet address owned by exchange, so they would most probably get the benefit from us keeping the token on exchange wallet.
I think it will be safe to put your tokens onto the wallet of which you are having private key and is in control.
