In fact, I managed to grab almost
30 blocks in 24h.

Sitting at roughly 0.9tBTC right now.
Even consecutive blocks a few times... I must have very good network latency or something.

Only a single Compac F hashing at just under 300GH/s.
That's 50,000 times faster than my CPU mining! Would you be interested to try? I still have a synced testnet blockchain running, and could give you access. At low difficulty, I wonder if I made a mistake for not getting anything in days.
