This is a good point, however the volatility is primarily that the space / projects are so new. The economic structure of each project varies, however most are designed so that if they are used for the utility they offer then they will have a price > zero. Due to the fixed number of coins in circulation the value should rise in some relationship with increased adoption & time (time due to deflation) Probably only a handful of coins will be used for B2C commerce. Notable other utility includes: > Decentralised storage (currently much cheaper than any company can offer) > Supply chain tracking > Website monetisation systems (without needing ads) > Smart Contracts > Create your own blockchain (backed by existing decentralisation) In summary: if it's used then a project should succeed.
