I am new to this and am experimenting. I am using Debian Sid and apt-get install installed the v013.0.4 version. After synchronizing, I started to mine using the
start_mining. After about 4 hours I mined a block.
Probably very very lucky.
I then upgraded to v0.14.0.2 (compiled from source) and then my reward from the previous version mined disappeared. I then restored a backup version of my wallet, but it shows 0 coins after the resync.
Did I lose my coins or never really got them?
