Did you notice that derivatives basing on ETH together with ETH may create a centralized role of ETH? This model is called 'creeping' war - step by step dethronement of BTC.
Nothing will be the same. Graham's Law in force:
https://en.wikipedia.org/wiki/Gresham%27s_lawDon't ever think of ETH winning the creeping war for now, because it's big price is caused probably by many ICO's out there that is happening or has been finished which mainly accepts ETH in their crowdsale. ETH won't win the war unless it has a hidden trump card to compete against bitcoin, which is unlikely because it still cannot be used to pay for services and goods online.
Right now a few major exchanges suspended Ethereum withdrawals
There seem to be like 300k unconfirmed transactions in the mempool (or how it is called in Ethereum) with fees skyrocketing. So, ironically, the only thing that Ethereum has likely been able to surpass Bitcoin in is the amount of money it takes to confirm a payment. I don't think this is the trump card you refer to, though it would be interesting to see how this coin is going to cope with these transaction jams if they become a regular thing like they are in Bitcoin nowadays. It kinda looks they should develop their own SegWit and Lightning Network
Ethereum definitely needs to scale but the congestion seen since yesterday is a temporary one due to badly made coin offerings leading to mass transations sent in a short amount of time.
Funny thing is ethereum already has a scaling mechanism but it is a very slow one to see results, each time a block is full the miner can increase the block size a little.
This is a good proof that Ethereum, together with BTC, can't handle any serious amount of transactions, meaning that it's also not suitable to be your everyday currency. ETH can be interesting for its tokens, ICOs and smart-contracts, but it's also quite centralized, and can't compete with Bitcoin in terms of being the best digital storage of value. Even if the Flippening will happen at some point, Bitcoin will still be relevant and will always have its own uses.
