I mined for Bluecoin years ago and had roughly 163,000 on an offline computer. They were on the native Mac wallet I had downloaded from the Bluecoin website. I have other coins on that computer and a couple times a year I'll sync the wallets up. I opened the Bluecoin wallet one day and most of my coins and transactions weren't there, but it was out of sync. I assumed they would show up when it synced up. I've had that happen with other wallets. I was never able to get them to sync with the network.
I just downloaded the 2.0 wallet and it synced up fine, but says I have only 430 Bluecoins. Does anyone know what might have happened to my coins? My 2.0 wallet has 2 transactions dated 9/8/17. All my old transactions from mining are gone.
