The thing is that only time can fix this particular problem...
That's what I've felt for a while is Bitcoin's biggest challenge. It needs to get over the image of an investment and move on to being a unit of trade.
But gold is worth something due to its properties, especialy in technical sence, unlike bitcoin, that has no other purpuse other than for trading/speculating.
If i was to invest large amounts of capital into something like that, i would like some guarantee that:
-it cant be stolen from me without option to file a claim (dispute)
-it wont be banned from existence
-cant be copyed by anyone, ever again.
And due to bitcoin nature as open source software, and ireversibility of payments, it simply makes me reconsider my investment.
I do have some portion invested in bitcoin, just in case something insane happens, but i realise how that is high risk investment, and so should others before they invest.
