Who is investing "more than they can afford to lose"?
You seem to be misquoting me. I was responding to Dafar's comment, and in your above editing, you seem to have attributed Dafar's comments to me.
The fact of the matter is that some people do invest more than they can afford to lose in a kind of gambling style... there are a variety of ways to accomplish such and a variety of individual stories.
You can borrow, also or otherwise leverage assets and/or credit.
If you're sitting there with $50k to pay for mom's medical bill and you instead convert it to bitcoins then yes, maybe that is not a smart choice.
Yes... these kinds of things happen when people have variations of gambling addiction issues.
For me, BTC/USD could go to $0 and I'd be fine. Hundreds of thousands of dollars worth of value lost but in 2 weeks I'll get a paycheck and can pay for my living expenses.
Well, a prudent choice with any volatile asset is to only invest as much as you afford to lose, and maybe you are doing it right. No matter what, with volatile assets, it does not seem to be an easy balance.. and the past couple of years have been quite a test for a lot of folks, including myself. I have learned quite a bit, and there are certainly a lot of challenges in terms of allocating money for bitcoin.
Even if you take a loan out to buy bitcoins, too bad for your creditor if it goes to zero.
Probably depends on the type of loan, and the kind of creditor that you have. If the creditor sends Guito over to break legs, then surely that kind of creditor will make sure that he is not the only one suffering.
