There will be a snapshot of the balances on the current MUSE block chain at a future date that has not been determined yet to migrate to a new MUSE chain that is a fork of Steem. It is advised to migrate your stake to the MUSE web wallet so that you are in control of the keys for the wallet that holds your stake during the time of the snapshot. It's possible the new MUSE chain will not honor the AGS / PTS balances that remain unclaimed, so time is of the essence! Below is a quick guide for accomplishing that:
I. Go to https://wallet.muse.help and register a new account using the web wallet. Make sure to save your password securely, and take frequent backups.
II. If you are holding OPEN.MUSE: Convert OPEN.MUSE from Bitshares / OpenLedger to native MUSE by sending to the account you just registered, using the "Withdraw" feature of the OpenLedger gateway.
III. If you need to import your stake from a BitShares 0.9.3c wallet: In the MUSE web wallet, click the Settings gear icon in the top right corner, and click the "Wallet Management Console" button. On the next page, click "IMPORT KEYS"
IV. Next, upload the 0.9.3c wallet and enter the password when prompted. Afterwards, if any balances are found, you'll be prompted to import them into the web wallet and claim them to your new MUSE account.
V. Lastly, don't forget to create a backup of your new account's keys. You can also perform this action from the Wallet Management Console.
If you've accomplished the above, you should be prepared for the upcoming snapshot! If you are running into problems with the Bitshares 0.9.3c wallet and have the file and key, do not fear! We can perform some surgery on the wallet to make it all better! Get in contact with myself in the comments below, on steemit.chat, or on Telegram @robrigo. Alternatively contact my friend fluxer555 on the bitsharestalk.org forums and both of us will be happy to assist in recovery of stake related to 0.9.3c wallets.
Please ask any questions regarding these instructions below in the comments. Also, MUSE is seeking more witness candidates! If you want to be a witness, read up on the project at museblockchain.com and join the Slack channel. Talk to @cob about receiving an invite.
Have a good day, and happy claiming!
