You have to read this blog post to convert your DDD tokens into PIN tokens.
If you don't do it on time, you may not receive anything at the end and lose your tokens.

thank you sir for information but i don't understand about schedule for convert DDD
"Schedule of converting DDD to PIN:
Starting from January 12, 2018 at 00:00 GMT: DDD holders can start depositing their DDD tokens to a wallet dedicated to the conversion.
Starting from January 22, 2018 at 00:00 GMT: PIN tokens will be distributed to your PIN wallet according to the aforementioned conversion rate, plus the bonus."
it's mean we only have 10 days to covert DDD from Januari 12 until January 22, it's that right sir ?
