Which changes of the hardfork?
Do I have to swap my coins?
There is no need to swap coins right now. Hard fork will be enabled, if "unresponsive" pools (bigmine.org) will generate high hashrate of old version blocks, which prevents switching to segwit.
If there will be a decision about hard-fork, community will be notified in all possible ways, so don't worry. Don't forget to update desktop and masternode clients to a latest version.
