We are still months away from any kind of relaunch/swap as it will cost more money. When that happens the burn fund will not be swapped, thus destroying it. We will give everyone ample notice when it happens. The details are not set in stone of what the road map will, be so nothing has been posted yet.
Currently the block chain is very secure. So I suggest people keep mining and staking for now, all credits held during the swap will be fully compensated.
