Do you have questions for the coming hard fork? We provided an extensive FAQ here: https://forum.cardano.org/t/the-shelley-hard-fork-all-you-need-to-know/36553

I think it is important to mention that, there won't be token swap, or a second coin or something similar at any time where you could lose something by “missing a deadline”. (this is also true for the rewards from ITN) I know this is very common in other projects, where they start with an ERC20 token and then that token at a certain point in time is worthless - people fear this quite often. In Cardano a lot of thoughts, work and time has been invested to ensure that such things are ruled out.
