My transaction from craptopia came through 4 hours after making the withdrawal. It works, but is slow, and everything else still sends/receives exactly as it always has.
So Cryptopia made good on their promise to enable clients to withdraw the funds from the crashed wallet. You have your SIGT so why are you still moaning.
I love that the craptopia response email makes a clear and simple statement that signatum "does not have an active dev," but the nonsensical diatribe describing their failure to implement the wallet explains that a dev physically visited, has been in constant contact, and claims to be informing the rest of the SIGT team.

Shows no activity since 23 July 2017
My suspicion is that craptopia is owned and operated by a bunch of teenaged computer nerds with entitlement and culpability issues. The whole response reads like a list of excuses for not having done one's homework. Could easily be reduced to "we couldn't figure it out. It kept crashing, so we gave up."
Cryptopia is a registered company with publicly available information about who owns it. Who is your coindev what is his name and address?
lazy idiots then smear the coin, because every failure is a blame game with millennials. Craptopia does not have an active dev. just a bunch of fat, lazy, extortionists, who think they're super smart.
Did your coin DEV help with wallet problems ? - NO
Cryptopia is an exchange - not a software consultant for failed shitcoins.
If the coin fails to meet the required quality standards and results in loss then it gets delisted.
Cryptopia had three developers working just on getting the wallet working - instead of doing core development.
