The fact you had to mine to earn coins and that became the basis for pseudo-anonymous transaction and the ultimate propagation of cryptocurrency, was the true innovation Bitcoin brought. Now, with ICOs, buzzwords, pump-and-dumps, and a new exchange every Tuesday, I feel like that sentiment has been washed.
The economic model of Bitcoin - to create artificial scarcity over time in addition to short-term supply control - was an incredible thought at the time. How do we move back to this model without the cancer of speculation?
That is expected to come and flood in cryptocurrency world, bitcoin is the very first cryptocurrency that made it as a great example or idea for the creation of other versions, system, usage, and features of coins or ICO's with the help of blockchain technology, you cannot stop nor prevent them from the creation of such things because we have our own ideas and motives in all things and there is no excuse for crypto to go for different paths whether it is beneficial to bitcoin or not.
