From
https://www.cryptopia.co.nz/Exchange?market=SIGT_BTC page just now:
SIGT / BTC market is closing
SIGT is being delisted due to ongoing wallet issues that remain unresolved, please withdraw all your SIGT before 2017-10-19
What? what does it mean for the coin value?
Could probably mean that all your coins in Craptopia is lost. Just opened a ticket asking how can I withdraw my SIGTs if their wallet remains unsynced.
30k lost...
