All of those things used to apply, the same as they do to REAL Gold (NOT "paper gold" )
However who "Spends" Bitcoin nowadays ? Anyone who really has some will either just be hoarding it and watching the price rise or will have sold it months ago for the cash. The points you mention are now all superceded by the fact it has become a bubble and has no real value any more.
You yourself keep saying you have had your money back out now, so you are "Risk free" - so it seems you do recognise the underlying impossibility of the price maintaining it's rise.
It's a shame because I like the principle of Bitcoin, but I suppose it is better for the "Powers that be" that it should evaporate in a meteoric rise and bust, destroying confidence in all similar items, than to make it illegal and push it underground.
