Bitcoin, a peer-to-peer payment system? Nah... more of a decentralized speculative investment platform.
Right you are! Bitcoin is more of an investment rather than a currency system. But that's what the mass wants. That's how a free market should function. When an innovation is launched and made it available to the mass, it's the public that decides the course of it. That's exactly what happened to Bitcoin as well.
Also, looking at the current situation of the transaction fees, Bitcoin is just not competitive enough to become a currency system. To be a currency system, Bitcoin needs to be cheap and fast, which is not the case. So take it as an investment only!
