@tabris I like and agree with your approach on the issue. Having only internal exchanges for SMT tokens does not make them look as trustworthy as having major exchanges also having the said tokens available for trade.

For example, look at the internal markets for Tron based tokens on TRXmarket. If it wasn't for their cooperation with Bancor, those internal markets could be shutdown or manipulated by the app token creators, and the token holders will not be able to sell/buy them on any external exchange. Kind of what happened in the case of Bitconnect.

Having SMTs on both external and internal Steem based markets would be ideal since it would bring more capital into the Steem ecosystem, and it would make the arb bot operators very happy.

Maybe the Bancor market integration would also be a viable option for Steem SMTs...
