I always hoard 80% of all the coins that I buy, just in case it does succeed in the future. < Important - Buy back those coins, when the price drop again.>
Damn yes, unless you don't believe on your coin, it's better to cut lose early yet ofc bitcoin is different story.
Buying cars or other stuff that depreciate is not a good thing especially you buy using bitcoin. Imagine how much now that car versus bitcoin. Well, I'll do the other way around, if I have a car, I'll sell it and buy bitcoin. That's more wise I guess. ;b
No, you totally misunderstood the point of buying that car. You buy "things" with value, to hedge against a situation where Bitcoin might fail in the future. Having all your eggs in one basket, is definitely a huge risk and you hedge against that by buying goods that you can sell, if something terrible goes wrong.
People still need to buy "things" with bitcoins or this whole network of merchants will collapse.
