Hi for a while now i have been testing ethereum capabilities and there is something i wanted to test and i cant figure how to do. When creating a contract of a custom token (using the code given in the ethereum official site) there is a sell price to set and a buy price for a token, in what way can i use this to give a token sell price of another token?
What I mean is, is there a way to give token A price in token B? essentialy making it possible to a user who have Token B to buy token A? and could a contract hold more than 1 kind of a token? like a contract that holds both token A and B? and maybe even more?
