Those are a lot of questions that no one have any idea what will happen.
The only thing that seems more plausible is that every user will have an opportunity to get the same amount of tokens you have now on the new blockchain.
But the question is if by swap it means we will have to send what we have to get the same amount on the new steem on tron.
It's still too soon to speculate on the consequences...
We have to wait and see.
Tomorrow we will have two main events:
Justin Sun Forum (https://dlive.tv/justinsun)
and the witness forum after it (https://steempeak.com/mspwaves/@aggroed/steem-witness-forum-tomorrow-immediately-following-the-tron-meeting-on-mspwaves)
There is not much we can say before these events.
