RE: This is WHY Bitcoin is the mother of all Bubbles. What you must know about Bitcoin now if you own it, or if you're thinking about buying Bitcoin (which many don't know about Bitcoin now). Must read:
Bitcoin is the first crypto currency it was never hacked like other cryptocurrecnies there are other features that make the bitcoin a very valid a nd robust currency - the crypto gold.
I like and own gold and as you say it will not cost 20,000$/Kg (50% less) in one year time but it will also won't cost double - 80,000 it just keeps its value.
I think the price of the bitcoin is undervalued.
After the uncertainty we have now - facing the fork, the bitcoin shows resistance at levels of between 2000 and 2800 (it was less than 2000 in the beginning of may 3 month ago) I cannot assure what will happen in the future but i am positive that in 3 month time we will not see the price of bitcoin at 2800 any more as it will go probably to 3800 and above , as the price of bitcoin is very volatile - when it will be "crashing " people will say bitcoin went below 3000 loosing 30% of its value and than back (like now).
when more and more people will be aware of the cryptocurrencies and will start buying bitcoins the price of bitcoin will explode.
already we see now that big funds are starting to have interest in the bitcoin
check this article here below - even the Rothschild Investment Corporation are buying bitcoins
any way ...only time will tell if bitcoin is a good investment or it is a bubble
