If they get their wallets working they have a chance to make it on the crypto market. If not, they will be gone by the end of 2019
The wallet worked. Isn't it? I get an impression that only few cases of holders that experienced unsynced wallet and that is because their nodes need update
I fixed it. I do not know what the problem is. but I needed to reinstall it several times.

Not on a mac. I have a few K of pot for a couple of years, and not one update is working. (the latest version is even impossible to install) 1. not syncing, after update , no balance anymore, recover an old wallet is impossible (on mac). Using wallet.dat file is useless too, cause newer version is not accepting the file. I can go on and on with issue's that have to be fixed. but as usual 90% of altcoins have no working wallet at all, and still think they can succeed.
I say again. I have multiple wallets across multiple windows based PC's for over a year, no issues synching or minting.
Problem is on your end . Maybe it's a Mac issue(like 80% of issues), maybe your OS is out of date, etc...
