Because ETH is at the root of so many asset backed tokens, the logical approach is to add a ethereum to your basket, and avoid the risky speculative coins, all the while diversifying into other settlement capable blockchains.
I think the ETH is a good alternative to bitcoin.
But the point is on the succeded to drive his hardfork to the right way until this time. And the validation of ethereum transaction is underestimated. It's too fast for a lot of people.
It can be main point ether is a good alternative for bitcoin.
I think ETH scaling is worst than bitcoin, if you check their fee and the delays, it may look like fine since there is almost no one making a trandsaction with ETH, Have they tried to spam attack their network for the network thresh hold purpose? I guess no. Besides ETH had been centralize token which is lead by its developer and can HF the blockchain whenever they wanted it
actually there has been some increase in the number of trasnactions made by ethereum network because of its pump and all the ICO scams that are running using this platform but you are asking a very interesting question which i would also want to know the answer to.
how will other altcoins (eterum and others) react to a spam attack, will they even survive for one week let alone 2 years?
