Worst place to ask this, I know, but... If I wanted to upgrade my old machine that currently has an HD 4770 (PCI Express 2.0 x16), where exactly could I find a worthwhile upgrade for less than $20?

Reddit's r/buildapc is probably your best starting point. It has a bunch of helpful tips/guides even for super low end builds.

#84Just took a quick look at this. If you are located in the 'mining valley' of Washington where power is ~2c/kwh you are still getting healthy profits. A computer with 7 GTX 1070 graphics cards should produce ~230 mh/s and draw 1 kw. This would cost approximately $30/month in power factoring in kw demand + cooling. The above setup will currently generate $385/month in ETH. So basically for miners who are in the right s…
Where do I check my raw kwh price? just on my bill? I'm in WA as well.
It will be on your bill.
It should also be published on your utility company website as well. At least my utility company posts rates on the front page.

#85All I can think of is the careless environmental impact of all that dirty electricity consumption. For, let's be honest, a mostly speculative activity. One cryptocurrency crashes, another gets hyped up, and the computational cycle repeats. When will it end.
Is the energy expended in crypto currency mining less valuable than that expended by the traditional financial sector?
It seems likely that crypto currencies transfer much less value per kilowatt-hour consumed.

With general stocks though at least you're investing in companies which make products, hire people, and hopefully stimulate the overall economy. A few Chinese guys in an old apartment building wasting power and compute/GPU resources... Not so much.

Can you clarify what "mining valley" you are referring to? Is this Chelan County?
If so I thought there was talk about a moratorium on new high load customers but maybe that never came to pass? See:

How does investing in a stock benefit a company unless you are buying from that company directly?

#89Earlier quoted context omitted.
Do many people live in units where electricity is provide as a gratis benefit? That was never my experience in California, Washington, D.C., nor in Virginia.
It can be rather common when a unit isn't in high demand.
Make extra profit every week... This is a great part-time job for everyone... Best part about it is that you can work from your home and earn from $100-$2000 each week ... Start today and have your first payment at the end of the week... ... http://www.joinmate2.com

#90Sorry if this is a dumb question, but does a single party control the difficulty level of Ethereum and Bitcoin? If so, it seems like they have massive control over the market. If not, how does it work?
The network collectively determines the difficulty based on how much compute power is being used. Specifically, it adjusts the difficulty up or down based on whether blocks are being found (relative to a constant expected duration) too quickly or too slowly respectively, which ensures the time taken to find blocks stays within a small interval. The specifics of how Bitcoin does it can be found here: https://en.bitcoi…
How does "the network" decide this? And what's stopping me from setting the constant to something lower in my own mining code? Does it follow that if most people in the network are duped into a ridiculously high difficulty, that it will be impossible to mine more BTC?
