Seems reasonable to me ....

A little off topic but not entirely, I think it would be a good idea to let sellers/traders choose what they want to get paid in. This will create seperate small markets within the main one we all use today.

Ex.

Seller A wants $1 in STEEM for X card and doesn't accept any other currencies as payment.

Seller B wants $0.90 in HIVE tokens for X card and doesn't accept any other currencies as payment.

Seller C wants $0.85 in DEC for X card and doesn't accept any other currencies as payment.

The above will create competition and arbitrage opportunities which very likely increases sales transactions which is good for the game. It makes sellers happy as it ensures they get paid in the currency they actually want. It makes buyers happy because we now have more choices and can search out the best deal with what currencies we have to spend.
