ETH completely proved to be a joke, it is a failure.

thats true, in my opinion it is not going to have a bright future and we will definitely not make any profit with it

Even if it is a failure you can still make some good profit with ETH, only if you know how to trade wisely.

Many people do not think the Ethereum is a failure. Look at the price, it is still over $10.
I think the price will rise after the DEV2.
