It is very disappointing to missed the swapping schedule because the old token will be worthless. Me too had the same experience. Because my mind was settled to hold the token for long term, I tried to forget it. Until the day that I'd visited the telegram group. Unfortunate for me found out that the old token was valid and the date scheduled had passed. Very disappointing feelings. My hope became hopeless and worthless. I learn that we should always make ourselves connected to the projects updates in order not to missed important thing.
