Is Bitcoin just another libertyreserve/e-gold/c-gold distributed competitor worth of couple hundreds of million u.s. dollars or is it really a new world-class currency that is going to change the world as we know today ?
If one compares the features, it's clear that Bitcoin is quite a different animal from libertyreserve/....
Yet this doesn't determine wether or not it will change the world as we know it.
This is the million dollar question and if anyone knwo the answer is yes they would not spend any BTCs of course 
.
.The answer is yes, unless noone spends BTC, then it's no
I'm sure a lot of people are holding on to large parts of their BTC. I am doing this myself... the possible gain in case of success is just too high
