Here is a great article:
http://letstalkbitcoin.com/bitcoin-and-the-three-laws-of-robotics/#.UrlH1rQ2nxF Note the third law:
#3 A DAC must protect its own existence.
Bitcoin is a DAC therefore
IT MUST PROTECT ITS OWN EXISTENCE.
Alt-Coins are considered a threat and a violation of #3.
Alt-Coins on one level support Bitcoin because if Bitcoin is destroyed there are endless alts just waiting. But they are also being used by the opposition in a very well thought out effort to destroy Bitcoin and all cyrptocurrencies. How is that? Because if currencies can be made to come and go even over a period of years then they will be viewed as unstable. They will not attract venture capital and the markets
all of them will fail.
What is the answer:
1. Bitcoin must maintain the technological lead or at least not get very far behind.
2. Bitcoin must maintain a strong dominant percent of market cap.
I do not see the BTC community very aware of this idea so I present it for further thought.
