I think it makes the most sense for Tron to connect to Steem using some form of interoperability. Like if you could somehow upvote content on Tron using Steem stake and vice versa... would be pretty powerful.
The economy of Steem makes a lot more logical sense than Tron. Tron's inflation mechanics are very odd, centralized, and seemingly unsustainable.
Regardless of what they are planning, Steem will catch a huge bid if people hear that Tron is involved. The amount of funding that Tron has is staggering compared to our Podunk network.
maybe a smt? would make sense and some cross chain action is also not bad IMO
