Any views on bitcoin? If you hold the view that the concept will gain traction, it makes sense that eventually one of these "currencies" will become the dominant one. Because of their headstart and solid looking governance, bitcoin is the most promising candidate at this stage, imv. Only 21m will ever be created (mined), as I understand it, so value of each coin set to increase. bitcoincharts.com/charts/bitxZAR and the exchange bitx.co.za A bit illiquid still, but it looks like a nice d/bottom in the making. Take a look.
Held since around R4/btc (2010? 2011?) but won't buy more. Cost me R300 and worth about R30k now. It's like electronic flaky gold - limited supply and varying demand, so value determined entirely by greater fools. Which is fine. If I were you, only put in some minor amount that ensures participation if it explodes in value but you won't feel like an idiot for losing. If you're looking to speculate, maybe look at litecoin or one of the others.
From what I've heard the actual currency might or might not win but the blockchain is likely to persist (as it has other technical benefits) so the price probably won't go to zero.
litecoin actually better tech and more secure, as is often the case the second dev is the better as it improves/fixed on the first .. and then of course there is dogecoin and heck you can even make your own crypto currency .. http://coingen.io/
