this shitty and bad and buggy windows desktop wallet (see my last 2 posts on the last page before this one) actually needs 25 gb on your hard disk!
other qt wallets of other coins need at most 2 gb (most of them even below 1 gb)!
so now i deleted this crappy wallet.
don't want to spend 25 gb of my precious hard disk space for such a suspicious wallet which doesn't work very good and doesn't even show you clearly what is your public address.
