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. <Big companies will kind of legitimize Crypto currencies, because people tend to trust these companies>
Do you think this is Good or Bad for Bitcoin, when this happens?
I don't know, I mean, what was the purpose of Doctor Nakamoto making the entire project open source? It seems like altcoins were encouraged. Bitcoin was most likely a proof of concept for the real innovation behind the madness, the blockchain. By making Blockchain technolgy a free to share code, it encouraged the startup of a grass roots community.
If I didn't know any better, I'd say Doctor Nakamoto's experiment was successful. An entire economy is being built around blockchain projects.
Just my two cents!
