Interesting.
I disagree with what he said, but he had interesting points.
First of all, you can hate bitcoin all you want.
It's like the first cell phones. They were great at their time, but now you look at them, and they just look clunky.
Because of the lack of changes in bitcoin, it's not useful as a cryptocurrency. People can invest in it if they want, but it's not cheap to transfer. That can also be good of course, as people won't be withdrawing willy-nilly. But they also won't be transferring it to an exchange to trade it back and forth all the time.
For actual use, to actually pay for things, you need something that can actually be transferred, with low fees, and speed. As long as bitcoin survives, it will not be the one and only cryptocurrency, unless they fix it.
But you also have separate use cases. We're on one right now. Every single one can have a separate coin, or one can fit multiple use cases.
Coins that don't have anything, in particular, to make them stand out, will likely go by the wayside. That doesn't mean there will only be one though.
But, if there had to be only one, the best candidate right now is steem. Fast. Powerful blockchain. Low to no fees on transfers. Perfect for apps. It's like a dream crypto.
Largely agree. Many seem to argue it's the best store of value, but I don't really understand the basis for that beyond "it's the original/oldest" coin.
