My tendency is to not agree with you, mostly due to your tone - see my note to vectorpush below for clarification.
Regardless, I hear you in that there challenges to be overcome to effect wide-spread adoption of this technology platform into the current financial markets. There is always a constant challenge in architecting, securing and operating financial networks. Innovation in these areas never stops, and it is unreasonable to assume we're going to adopt something long term that is insecure or outright broken. We are driven by trust, greed and fear, after all. I don't trust you and I think you are going to steal my money. I love my money, so I will take measures to protect it long-term.
Bitcoin is complex, and I've observed people having difficulty digesting the details on how it works. One thing of value that appears to be overlooked is the fact that Bitcoin is being secured by individuals (miners) putting power into the system. That power is used to compute the encryption used to secure the coins. Some have put the time to crack a single bitcoin key at 82 billion years.
The fact that Bitcoin is secured via power put into the system, currently around 7 quadrillion hashes per second, needs to be considered when discussing adoption trends. The value brought to this market by that computing power cannot be ignored.
It is, to put it succinctly, a platform of trust powered by the most massive compute engine humanity has ever built.
