I believe altcoin has a future, and it all depends on every developer and team behind it. This has been proven by many investors who became rich by it. and newer altcoins appear, this is evidence that potential altcoin business in the future.
my friend is also one of them because he is an early investor of altcoins and now he is already wealthy because he manage to earn big by just trading alts , therfor i could say that alts do really have a potential to succed in the future. although bitcoin is more popular to be known as the future of money.
There is a whirlpool between bitcoin and altcoin indicating that the altcoin value is easily degraded for the evolution of bitcoin and eth. Some times bitcoin starts to show signs of speeding up, altcoin is the coins that is losing on price when it is boosting the deal. It's about value. But for the purpose of its use, it has practical implications for innovation. The problem here is that the user needs are balanced by having too many coin's have good performance. Then the growth of altcoin will slow down.
no it is not true. bitcoin doesnt hold the value of altcoins , some times bitcoin is decreasing but altcoins were still rising . There were also time that both of them are decreasing . Therfor there is nothing real relation between them.
