What's wrong with the new wallet ? It's up to date (latest block) and yet still using all of my bandwith all the time for apparently no reason. Both safecoind.exe and safewallet.exe are downloading non stop.
I think one problem is the Safecoin devs didn't code the wallet, and are not fully aware of how it works.
It's a shame they don't fully understand the interest mechanism, and ignored concerns about problems with their implementation of the wallet. Enjoy working though your fork.
I would stick with a coin that pays interest.
