if mining will stop bitcoin will die,blockchain will not work anymore,it is biggest bitcoin problem to solve if btc want to survive
Makes no sense - if 90% of miners quit, difficulty goes way down and all of those old ASICs come out of the closet, even with a much lower block reward...
I find it more appropriate to compare Bitcoin to a company and the users to customers. (We are essentially buying the "product" after all, with with fiat or through time and effort to mine it, or through trade - opportunity costs). In that lense, Bitcoin is a decent sized company (7 billion dollar market cap) with a fairly sizable customer base that seems appropriate for the market cap. It certainly has room to grow, but it could also stagnate and lose market share by losing out to competitors (alt coins) and failing to stay innovative.
This is a good analogy, but remember however that the traditional customer/vendor model is different in several ways:
* The customer doesn't usually build the company other than buying the product and possibly evangelizing it. So mining and running nodes is not part of the normal model.
* The product in this case is also a medium of exchange - in theory this product could be bartered/exchanged to acquire countless other products.
* The company has an unconventional management structure that requires consensus to upgrade the product.
On that note, IMHO bitcoin does not need to stay innovative - it needs to stay STABLE. An innovative currency is a high-risk speculative instrument.
For example, I think ETH is a giant pump-n-dump for pseudo-smart people, but what do I know... Let the altcoins test out innovations, let's keep bitcoin solid and trustworthy.
Really, the "management" structure isn't all that unconventional. It requires consensus, same as any board of directors voting on proposals of a company. The way the voting is done is unconventional, sure.
On the topic of innovation, Bitcoin will absolutely be replaced if it doesn't innovate. The fact that the block size cap was not addressed since inception threatened to sink the entire system. Even the solution employed now is only a temporary fix. It will run into scaling problems again. But that's more of an infrastructure problem than an innovation problem.
Other alts have a market because they're addressing something bitcoin isn't. In the future, bitcoin may be too slow compared to alternatives. The blocks may be too small. The amount of information able to be recorded in the blockchain may be too limited. It can't handle smart contracts (not sold on this idea anyway, just floating it as an example of a potential disruption). There are a myriad of unforeseen circumstances that treaten Bitcoin's dominance in crypto. The fact that the system can't address infrastructure problems doesn't instill any confidence it can adapt to a changing marketplace.
The one thing Bitcoin is not, is flexible or nimble, just like any other market dominating entity. It's afraid to rock the boat and threaten it's current market share, which is exactly what makes it ripe to lose it.
