I don't agree with a couple of your comments. Whilst your comment about the stakeholders may have been true in the beginning, I think the people you have mentioned are being squeezed out, and they are being replaced by bankers and investment trusts.
I think you are under-estimating the capability of the people who will build or are building crypto based products. At the same time you are over estimating the importance of bankers or investment trusts. Bankers are a reality but value creation cannot come without crypto becoming something bigger than another wealth management tool. I also understand that this may seem as an overly optimistic view considering the range of scams and vaporware that has made the rounds in name of blockchain innovation. Yet, the bankers/ big money still wants its stake so it doesn't miss out when real value creation starts.
Bitcoin is a unique product, and there can never be another equal creation. --snip--Now that the technology is understood, any product that attempts to emulate Bitcoin will become the victim of such an attack.
The new products don't necessarily have to emulate bitcoin or compete against it. In fact, Bitcoin was supposed to enable these innovations.(Till Ethereum became the next best option(. As far as developers are concerned (Both the sincere ones and the scam-artists), Ethereum has leveraged this better than bitcoin.
The usage case is another interesting point. Bitcoin was created with restrictions that appear to be designed to prevent it ever becoming a volume global payment system - the 10 minute block generation time, and the 21 million cap are two examples of this. However, it is a tremendous system to use as a store of wealth, and a means of wealth exchange, and in this instance, it is very similar to gold. In the same way that gold was used to gain initial credibility for the fiat monetary system, Bitcoin can be used to build a fast micro-payment system based on an underlying asset value. However, you can bet that once it gains acceptance, the bankers will be there with fractional reserve banking. We can already see this happening with some exchanges. It is for this reason that I will only leave trading funds in an exchange wallet. I'm about to move my Bitcoin out of my CoinBase wallet, and into one of my HODL wallets. This is not a reflection on CoinBase, as I think they are one of the more reputable exchanges, but a reflection of my opinion of the whole banking ethos. An exchange is basically a Bitcoin bank.
The oft-quoted comparison with Gold is apt but incomplete. Bitcoin is so much more than just a micro-payment system or a store of wealth. I agree that exchanges are basically Bitcoin banks. In fact, that is why exchanges are the ones which are fostering the most competition in cryptosphere. They are doing this by listing coins left, right and center. And allowing fiat on-boarding for more and more pairs. Banks ultimately need assets they can invest into. In the process, they foster innovation/ entrepreneurship. I'd mention again that my view may sound overly optimistic, but that is what the exchanges are doing.
