I just got reply from Swisscex team, they have upgraded the wallet to 10.3.2, thanks for their effort!

some people reported that they can't finish syncing when using 10.3.2, i will try my best to fix it and make sure all people can finish syncing without a long time.

i'm doing experiment on concurrent sync now, testing result shows that the speed of concurrent sync is much faster than 10.3.2, but i need more test before release.

concurrent sync is a new technology in cryptocurrencies, Pennies will be the first one to use it.
