Hi guys,
I got my ledger nano S stolen last week as it was inside my bag. There was 4 Ether on it. So I've tried to recover the Ether using the seed phrase.
Bitstamp is stated on the ledger website as one of the wallets to do this with. After successfully recovering the wallet to Bither, I realised Bither only supports Bitcoin. What has happened now? Did it physically try to move the Ether in the blockchain to the Bither wallet?
No. If Bither doesn't support Ether, then it didn't touch your Ether at all.
Or did it only try to move any Bitcoin that was in the wallet. (which there wasn't) What should I do now?
It probably didn't try to move anything.
It doesn't state clearly online which steps to take to secure the ether to another wallet. Can I still restore through other methods or are the Ether somewhere with Bitstamp?
Unless the bag thief has figured out how to steal your Ether, they probably haven't moved at all yet. You need to find an Ether wallet that supports the same 24 word seed phrases as Ledger so you can recover your Ether there. I don't know much about Ether wallets, but certainly you should be able to buy a new Ledger Nano and recover to that.
