I too have been unable to move any substantial sum of DSH out of my wallet. I have resynced the blockchain and reset my wallet and although I can always get them to show back up in my wallet, I can never successfully get them sent anywhere. Very small amounts will send, but even the larger amounts that are failing are much less that the max TX size. If I have a few 100M DSH to move, would I need to do so over 1000's of TXs?
i think at this point its limit safely is 4 million at a time. i never have issues sending that amount per transaction.
I tried down to 1M and it was still failing to send after a few hours. Now, only at <10K does it send normally. Something just seems off as in the past I have had no issues. I have not sent any DSH since the last update though. Or maybe something to do with Poloniex?
