Hi Bitcoin Experts,

I was playing with bitcoin core v0.1.0 (really first version released back in 2009 or 2010).
I kept the software running for one week (mining) and when I looked back, I saw 600BTC generated.
I have sent those BTC to couple blockchain addresses, but never worked of course.
I know that newer versions of bitcoin core does not allow mining anymore.
The balance on my bitcoin core v0.1 show 50BTC and couple sent transactions...


Now, when I imported the wallet into bitcoin core 0.15, the balance says 0, but i can see the same history on transactions.
The transactions say: "0/unconfirmed, not in memory pool".

Any expert explains to me what I was exactly doing and what did I generated exactly?? How did the very first versions of bitcoin core synced to blockchain?




Big thank you!
