1. The whole idea that someone can turn on his computer/GPU and "bit mine" and earn money is ridiculous.
People should earn money when they work hard for it. Turning on a computer and leaving it to run does not and should not count.
This is a waste of electricity as well and therefore it causes greenhouse gases and has a carbon footprint.
2. One would think they came up with a new currency system so theft could be prevented. No, BC gets stolen all the time.
Why couldn't they "disable" the serial numbers of the currency that was stolen? Thats the kind of system that should have been designed.
3. BC is unstable. People lost a lot of money (one tiny example; there are probably hundreds and thousands) and they did nothing wrong. A good modern currency should not have this defect.
It does have positive points which is why many people are using it but it would have been nice if it didnt have the above problems.
One would think if a new digital currency was created it wouldnt have issues like this. Computers and software are so powerful now. It should have been possible to design a currency with none of the issues above.
"Then dont use it" Or "Why dont you make your own currency system?"
These are not valid responses so they shouldnt be said here.
My rebuttal:
1. No, it's not ridiculous. Day traders have been doing it from home for decades. People that earn money through their computers or technology really are earning it. It's not a waste of electricity and if anything it will only become more efficient than it is today.
2. I actually agree with you on this point. This is the point of technology: solve problems. I don't doubt that there are already coins with this in mind.
3. Yes, bitcoin is unstable. That's really good for traders. Enjoy it while it lasts. If people don't understand the instability and risk then they should not get involved with bitcoin. That's more of a personal decision but not really a detractor of bitcoin. It's only a detractor if you want a low risk portfolio at this time. But then again, bitcoin has been going strong for years so it's actually continuing to prove itself as viable and getting more integrated with various ecommerce channels like newegg, tigerdirect and overstock.com
