if you can sell it (even for 1 sat) and buy sat 2 on cryptsy or mintpal you will get a lot more coins that way (if the price will stay below 1000 sat per sat 2)
SAT was meant to be offline after 7,777,777,777 pow coins were mined, blockexplorer states that 7861200370 coins have been mined.And if any coins were mined after the transition to pos there`s no reason to change your SAT to SAT2.That was the point, but if you can trade sat for btc, doge or ltc as in comkort and it`s profitable,then way to go
