I though Poramin had already upgraded wallet so that it doesn't lag and so that it syncs faster, it seems like this coin needs a Dev team behind it, because poramin on his own it makes it a little difficult for him.
I have downloaded the poramin version but it's so lag and now it's over 24 hour and I see that it was stucked at block 13189 (12 days to go).
How can I do it? how long must I wait for synchronizing?
First loading might take long due to the node. You could add xzc.suprnova.cc node in the mean time for faster loading. We will try to upgrade our seed node but it's not a priority now.
