Well there are many voices out that that consider BTC more as a “store for value” than anything commercial. Like virtual gold or something.
I know there are 1000s of alt coins out there, but only a very small number of them today have any real following. Most of them trade on the etherium network; with ETH (ether) being the most prevalent currency. I do have a small number of ETH in a couple wallets somewhere. Maybe worth something in dollar terms, but not life changing money. One of those shoulda/woulda/coulda things when I had the chance I just nibbled when I shoulda gone whole hog.
All said, there is a great future for blockchain tech, and BTC being the first and biggest in value it gets the headlines. I think that will change. They even now have etherium tokens that trade on parity with dollars, and one that trades with parity to BTC. Ultimately blockchain technology will change nearly all kinds of transactions. The battle for the coins is something else.
Bitcoin and etherium are two very different systems, used for very different things. Bitcoin brings with it the public ledger and scarcity. Etherium is the base for many other digital currencies, and the foundation for digital contracts.
They should coexist quite well for some time to come.
