Recently I have observed that for every pump or increase in price of bitcoin, there is no corresponding increase in the price of altcoins
Even though this causes a lot of people to worry, it is best as it prepares altcoins for self dependence and it also limits manipulation of altcoins
Soon enough both bitcoin and altcoins will be non dependent on one another totally
Well, I see it as a good point : the market is going more mature, and value more the value of Bitcoin rather than other alt/shitcoins. Investors are fed up to buy on promises, now they want to buy when a real product is launched; so unless these altcoin will have a go-to-market strategy you might not see them following any bitcoin pump.
