If altcoins aren't dependants on Bitcoin price or value one altcoin would have over throne Bitcoin, if it was a different story that altcoins don't rely on Bitcoin bullrun I believe Bitcoin won't be the 1st today, am I wrong or right?
You're true about that. The fact that the value gets centralized into the bitcoin and the story will be different if altcoins can stand with its legs without any intervention from the bitcoin but it looks like this thing will never happen unless altcoin can create a mechanism to secure its value from the intervention of bitcoin.
Any coin can create its own value just by having some real world application and continuous user for it. It means that any coin can stand on its own legs if it is having continuous buyers. I believe this is not right to call bitcoin is intervening on values of other coins. We are just using bitcoin to estimate the value of other coins which means bitcoin is being used as a reference value and nothing more. As we all know, bitcoin is being valued in terms of USD which doesn't mean that USD in intervening.
