Sooner or later they will reach a breaking point. In 2 - 3 years I think some of them would have to dump if no bank or company uses the Ethereum blockchain. We've seen this happen to NXT, Bitshares plus others. They just fell from the top 10 at coinmarketcap.
Ethereum has made regular disingenuous claims just like NXT and Bitshares did. I agree with your assessment where Ethereum will fall from the top 10. If you trust serial liars then you're asking for your money to be stolen.
- Vitalik Buterin claiming he would write his own programming language from scratch, which he has yet to do and never mind it took languages like Java 10+ years to work out the bugs and train developers.
- Ethereum spammed about IBM Adept, but Paul Brody has left IBM and Project Adept has been canned (AFAIK).
- Dapps was spammed like the second coming of Jesus, but it all amounted to illegal gambling apps and the internet is already full of them with millions of users and there's no reason for those users to go to Dapps.
- "Smart Contracts", more like "Smart Theft", which put $150 million at risk.
The red flags were present in Ethereum before launch. Some Blog Editor who was passed off as a programming prodigy (when all he had were media connections, at best). PhD Philosophy founder whose prior employment was a bankrupt DJ sound company. Other staff at Ethereum, according to their linkedin, hadn't work a day since DotCom...
Call it what you want, whether it is hype or scam, but Ethereum is just
plain bad.
The red flags were there before the launch, why did people invest it. Also why do miners still securing the network?
