Test Mastercoin properties have the most significant bit set to distinguish them from real properties, and they cannot be traded against real Mastercoins nor otherwise interact with non-test properties.\r\n\r\nRelated to crowdsales there is an additional line, even though it's not bound to the transaction definition itself, but can be found in the general smart property description:\r\n\r\n> The Ecosystem for the property must be the same as the ecosystem for the \"Currency identifier desired\", i.e. both must be in the Mastercoin ecosystem or both must be in the Test Mastercoin ecosystem.\r\n\r\nI expressed several times how I dislike the ecosystem distinction at a whole and also suggested in another issue to define all relevant rules right where a transaction type is defined.\r\n\r\nBut that aside, something similar does not exist for [tx 21: Sell Master Protocol Coins for Another Master Protocol Currency](Sell Master Protocol Coins for Another Master Protocol Currency) and since this topic wasn't discussed until now:\r\n\r\nHow does this play together with token-to-token trades? Are trades between ecosystems allowed or not? What about the (maybe special) case of MSC vs. TMSC?"}}
