I opt for bitcoin because it has more utility value for me.
My bank makes it an enormous pain in my ass to buy things from overseas vendors; they won’t process any payments that are going outside of the US border. The rationale is ‘fraud’, even when you’re dealing with well-known and trusted vendors. Even when I try calling my banks and telling them to pre-authorize the charges, they won’t go through. The only way I can get around that within the established financial system is by using a 3rd party payment service; those 3rd party services make their money by lopping off a percentage of that purchase. E.g., if I’m buying something for $1000 from China (and we’re going to ignore tariffs, duties, taxes, and shipping costs for the moment), then I may have to pay $1040 for it, because of the fees that are taken out. On the other hand, if I’m buying from a trusted vendor, and I use bitcoin, I can just send it to them. Bitcoin doesn’t care where it’s going, and–assuming you don’t care about speed of confirmations–transaction fees can be quite a bit lower than using any other payment system. (And, BTW, transaction fees are built into all payment processing systems; it’s just not apparent to individuals on the purchasing end. That means that if something costs .001btc, then I have to send, say, .0010001btc to the vendor, but then the)
Speculation doesn’t play a role in it for me.
I have no direct use for gold; I can’t plate connectors.
It’s mens rea, lit. “guilty mind”, e.g. intent. If you take an action with the intent to cause a death, that’s murder (in my state, that would specifically be malice murder). If you take an action that is likely to cause a death with reckless indifference, but not intent, that’s usually something like murder in the second degree. If you cause a death through negligence or by accident, that’s usually some form of manslaughter.
Most traffic accidents are negligent; people don’t (…usually…) get into a car with the intent to kill someone, nor are they usually driving in a way that the know is likely to cause harm to other people. There are obvs. factors that will affect this–such as driving drunk–but causing a death is usually unintentional, and not through reckless indifference.
