Diff retarget time of 1.5 days is killing the coin. We are currently on block 12820 and from what I understand the diff is set to change every 864 blocks (1.5 days) which means the next block change is at 12960.
With the average time to resolve a block currently at 2.6 hours, we are currently looking at 15 days for us to reach the next diff change.
Of course once we get to the next diff change, the diff drops and megahash comes in raising the difficulty again for the next block change, which will again take another 2-3 months to switch when the hash rate drops against the raised difficulty. At the current block solve times, the coin is extremely slow to send and confirm.
LTCD went through a similar issue, and the issue was resolved by implementing dynamic diff retargeting which was only achieved through a hard fork. I believe the dev's need to do the same thing.
