There is many More better blockchains with much better use Cases and utility.
ETH is one of biggest.
Btc is still alive only reason for that is some very powerful and influenceal people want btc to be alive there is no use Case no utility other then speculation even to Move dark money btc is not good even to make Transactions between companies not good.
So I guess btc is alive only that some big important rich person Can speculate and dump btc on poor suckers.
So to Say to take money from people and scam them.
There are blockchains such as Cardano and NEO which are superior to Bitcoin. But they will never be able to take the place of Bitcoin, because first and foremost the users are concerned about security. The PoW algorithm of Bitcoin makes sure that the coins are secure while being transacted in its Blockchain. If something has worked well for more than 12 years, you are not inclined to replace it with another asset, unless the supposed replacement is drastically better than the original one. And from what I have seen, none of the altcoins have some revolutionary new idea, which makes it necessary to switch from BTC to that coin.
