Can anyone tell me what i can do with the old shift coin ? As i found a few old shift coin on my old laptop. The last block synced number is 946835
When did you get the SHIFT? If it was before the switch from Ethereum codebase to Lisk codebase (I believe this happened end of 2016 or early 2017), then unfortunately you are probably out of luck...
If it was after, and you have your passphrase you can just enter it at
https://wallet.shiftnrg.org/ to access your coins.
