Investing in Canary Networks

I've done what I'd call general research into cryptocurrencies and believe canary networks are a good place to invest in. Canary networks work as a playing field to test functionality and possible economic scenarios before taking them to the main network. I notice that some canary network coins are at very low prices right now. Surely a canary network can not fail if the main network becomes successful. Could a canary network coin be seen as the younger half-brother to the coin it's being tested for? Did I happen to come across a diamond in the ruff? Do more people not know about this or am I missing something?
