The only way ETH keeps up with Cardano is through another hard fork.
Yep so investing in ETH now, doesn't really help with one of their forks in the future.
You've got it totally wrong, ETH is not keeping up with cardano, cardano is trying to keep up with ETH.
Cardano supporters are all claiming how it is is such a better platform, especially on paper.
Well, that is the biggest problem with cardano, it is only on paper.
The crypto market has already ballooned this past year and is set to pop in 2018/2019. We are past the point where whitepaper projects can survive.
Is cardano a better platform than ETH? Undoubtedly yes, but is that enough for it to overtake ETH? First, the platform needs to be released. Then it needs massive real life adoption that meets than exceeds eth, then, the most important, it needs liquidability. No matter what, ETH has an insane head start.
It's not always the technically best projects that will dominate. Just look at BTC, we all love it, but there are so many better blockchains out there with better scalability but BTC still crushes them all.
Yep, that's how speculative investment works. You try to figure out what is going to be big in the future, not what is already big. Hard to make money on stuff that everyone already knows about.
