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.
It's not alive just because some influential people want it like that. It's alive because there is a really high demand for Bitcoin. And it's adoption is becoming bigger and bigger in time. People like Bitcoin because it seems like it's special among cryptocurrencies as it's the oldest one.
