Perhaps it cannot become a currency, but it certainly can become useful money. And with Bitcoin's nature, not only it is scarce, but also it can be pretty damn liquid too.
In fact, equally liquid to bonds, stocks and other financial assets that are traded on the free market.
Criticizing Bitcoin is not that interesting though because the argument of the limited supply, transaction cost, reward distribution, etc., is pretty much known. And yet, if people still use Bitcoin, it is not going to disappear anytime soon.
It's probably more interesting if you try to explain what is your idea, about your system, about the ideal cryptocurrency in your mind. Preferably about the economy so you can post it here.
Nice writings by the way.
I surely will. I just need to explain some premises not to turn it into another discussion about the reasons why Bitcoin cannot achieve the same.
