We are less than 9000 blocks away from POW ending. My goal is to be in the top 15 richlist before POS kicks in.

I'me # 6 on the rich list. If i combine both my addies I would be #2 under the 2.5 mil guy. I have close to 5 mil coins.

Top 15 is great spot, good for you.
I'm a small miner and i started mining late (after block 50.000), but I drill very hard, my rigs are always on the edge of selfcombust
So i would be pleased if breaking in top 30-35.
