Quote from Scataphagos:
How can the value of money fluctuate so much? After all, you're changing your $USD into bitcoins for whatever reason. How can they be worth 50X what you paid for them at a later date? If that's really how it works, the risk is HUGE!
It's not like buying value biotech stocks where you hope their business and earnings justifies a big price rise. Bitcoins is just exchanging one currency for another. ??
I'm not sure I quite understand. As with the purchase of any asset, the most you can lose is 100%. If you exchange $600 for one Bitcoin or $600 for 6 Yen, in both cases the most you'll lose is $600. The only difference is that Bitcoin fluctuates more than JPY.
The comparison to biotech stocks is valid - there is the potential (however small) for Bitcoin to be a game changer and replace fiat currencies as a medium of exchange. If that's the case, then $600 is cheap.
