How to mine CPU coins for free

[btc_artist]

I've been mining on the micro instance for a couple days now.  I'm not getting much out of it.  The speed fluctuates wildly.

What's your average speed and what currency are you mining?

And is it staying withing Amazon's limits for the free service?  Or will you be billed?

Free tier has 750 hours of EC2 running Linux/Unix Micro instance usage per month. So if you have one micro instance you can use it all month 24/7 for free.

Right, but do they not also have limits as to how many CPU cycles/processor time you can use in the free tier?

[Adamlm]

No, they don't count CPUs nor instances but HOURS. You have 750 hours per month. 1 instace 24/7 = 24*30 = 720 hours per month - it's free. 2 instances = 2 * 24*30 = 1440 - 750 = 690 hours to pay etc.

Here is a nice calculator for this:

And about a micro instance:

Micro Instances - Instances of this family provide a small amount of consistent CPU resources and allow you to burst CPU capacity when additional cycles are available. They are well suited for lower throughput applications and web sites that consume significant compute cycles periodically. Micro Instance 613 MB of memory, up to 2 ECUs (for short periodic bursts), EBS storage only, 32-bit or 64-bit platform.

With the current LTC difficulty (0.61881515), LTC price (0.015984) and 1 khash/sec, you can make $0.78 per month.

The average seems to be about 0.30 khash/sec or so, though, which would be $0.23 per month.


Unless you can get at least 1 khash/sec, this doesn't seem to be worth registering for.
