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.
Bitcoin will never die because it is the first cryptocurrency to introduce in the world and have the largest value amongst all of the cryptocurrencies now that have been introduce. Being shock that you thought bitcoin is dead, i think you do not have any bitcoin or atleast a little amount of bitcoin in your wallet. Having bitcoin now is hard to earn because its value goes higher time by time and even etherium value is also high now.
Unlike before where you can buy Bitcoin in a much cheaper price, now you need to invest decent amount of money
to hold portions of bitcoin in your wallet.
Like what you said, it's the first crypto being introduced and there are many institutions who are now working inside
this industry, dying is far from reality.
