I think the immediate reaction from people invested into Bitcoin would be negative, when they hear that some new Alt coin or "Blockchain" based technology was launched. You immediately think that money will flow away from Bitcoin to these Alt coins and Bitcoin will lose investors.
Could a new coin attract new investors to the whole Crypto currency scene, that would not have invested, if it was not for this coin?
Let's say for instance "Mc Donald's" launch a new Alt coin, called "McCoin" and Billions of people starts to buy and sell these coins. What would the natural spinoff of this be? I think "increased awareness" of Crypto Currencies. A percentage of these people might start to trade other Alt coins or Bitcoin as a result of this.
Do you think this is Good or Bad for Bitcoin, when this happens?
In the case of the coin that you are describing it is impossible for it to have a bad effect on bitcoin because it will be a very specialized coin with a very specialized use, but it will have the good effect of promoting cryptocurrencies and promoting its use and since bitcoin is still the most widely used cryptocurrency bitcoin will be the biggest winner in such a scenario.
