Could someone confirm hashrate with an Amazon EC2 32CPU instance please? I was getting approx 1,300,000 (if I remember correctly). Is this in the right ballpark?

You are referring to c3.8xlarge ?

Yes, c3.8xlarge.

I've seen this given as the hashrate to blocks calculation:
hashrate*86400/difficulty=blocks per day

If that is correct, one 32CPU EC2 (c3.8xlarge) instance at Amazon with 1,000,000 hashrate and difficulty 139,885,237,143 gives:

0.6 blocks per day.
10BBR per day.
0.015BTC per day.
Given $670 per BTC, you've mined $10 worth.
And you've given Amazon $40 for the privilege.

That's a $30 loss.... Where have my calculations gone wrong?!

Typical miners concerned only with selling now and not holding Roll Eyes

Nope. I'll be holding. Thanks for your concern though. I'm trying to figure out why people are selling, since it seems like they are selling at a loss. Can anyone sanity check my calculations? It seems like buying at the current price is the cheapest way to acquire more BBR.

With a home CPU you get a hashrate from about 500,000

0.3 blocks per day
5 BBR per day
0.007BTC per day
Given $670 per BTC, you've mined $4,60 worth.
Elecricity is 2.7 kWh for one Day.
May you pay 0.10$ for 1 kWh it cost you 0.27$ on day.
That's a $4 win.... Where have my calculations gone wrong?!
