We have to take into account that this would only be a test scenario, which would only serve for personal experience and knowledge.
I guess I just have a hard time understanding why anyone would want to spend money on a completely futile practical experience, while you can learn more without the hardware. I learned a lot about (CPU) mining
around this post, and reached higher hash rates than this Nerdminer.
LoyceV, you are only looking at the mining part and the possible return on it.
I already know what it's like to mine bitcoin directly with GPU, that's how I got some satoshis in 2013-2014. But, I never had the opportunity to mine with an ASIC or other specific equipment. I would like to have this opportunity, but the machines have absurd prices - even the used ones, in addition to the current energy cost. So, acquiring this type of equipment and doing some tests, with a low cost involved, is a more or less practical way of being involved.
Another point, in this case I am talking about using solar energy, it can be an excellent way to train DIY on this topic, test various setups and check how everything works. This could develop other ideas or even projects that are much more relevant to this area or others.
When you read about the subject, you will never understand in practice the problems or doubts that may be involved. You will read about them, and you will even understand how they were resolved. But, you don't understand why these problems occur, because sometimes the cause or solution to a problem has several variables.
This ends up being the same as driving, you can read, watch videos and even play driving simulators. But sitting in a car and driving in reality will always be different. Theoretical experience will help you in many things, but it will always be different from practical experience, which is much better.
