We have already analyzed the first major problem, which lies in the scarcity of the supply. Satoshi supposed that limited emission would make Bitcoin much more attractive in contrast to constantly inflating fiat currencies and we cannot state that he was wrong about that. The problem is that Bitcoin simply turned out too attractive to perform money functions and became a hedging and speculative asset instead.
The second problem lies is in the model of the system’s support and particularly in the reward distribution scheme proposed by the creator.
I think those "problems" can be addresses in a more simple manner. The simpler solution is usually correct.
1 - The problem is that Bitcoin simply turned out too attractive to perform money functions and became a hedging and speculative asset instead.
All fiat currencies can be speculative assets. Why bitcoin can't? There is a whole financial market called Forex, which is based on fiat currency trading pairs such as USD/EUR.
2 The second problem lies is in the model of the system’s support and particularly in the reward distribution scheme proposed by the creator.
The reward distribution is basically a fee paid for a service (securing the network, through mining). The incentive will last only a few decades, which will also generated new coins and properly distribute them alogn the years.
