The idea is to be able to convert something like mora coin to geffen arena coin, or gray shard to honor token, and things like that, but we need UNIVERSAL TOKEN as a bridge to them. Of course the amount needed will vary depend on the subcurrency. Let's say
10 mora coin -> 1 universal token
25 geffen magic coin -> 1 universal token
5 geffen arena coin -> 1 universal token
then, universal token can be converted to any of subcurrencies, with lowered efficiency.
1 universal token -> 5 mora coin
1 universal token -> 10 geffen arena coin
1 universal token -> 2 geffen arena coin
