Hi dear user,
First of all, sorry for being late. Because our team members are in China, and you know the GFW, we does not check bitcointalk forum often. You don't need to worry about asset security.
It's suggested to use android version of Bither rather than desktop version, since the desktop version update is lagging behind the android one. We just released a new version v1.8.6, and it was tuned for the performance of importing private keys and reload transaction data.
Important tip: the Bitpie Wallet (bitpie.com) is a multi-chain wallet developed by us following bither, which is easier to use, so we strongly recommend you to try Bitpie instead of Bither.
