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 Maybe it's a Mac issue(like 80% of issues), maybe your OS is out of date, etc...
Just a bunch of BS!!! Imac is up to date! 22 other wallet, of real coins, are working fine on this imac. latest software updates checked every day. So in my humble opinion there is no serious dev behind all this. The basics of having a succesfull coin, is having a flawless (client) wallet running cross platform with a good GUI. so my advise ; if you still have acces to your coins, sell them, if you can, during the next pump, and stick to BTC. Time to go for some real pot.

Cheers!
