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?
The issue is rarely with the exchange. The most common issue is the transaction size being too large. Increasing the fee to 15 DSH in your transaction will help.
