How do you see ETH future as currency?

Lets hope so im all in ether atm , i think its awesome what they are doing

Just the market cap (coin amount) will grow a lot more

Yes, constantly.

Privacy

Buterin pointed out privacy is the another major factor which makes the blockchain unsatisfactory for at least some use cases. He said: "You know companies are all interested in blockchains, they love blockchains – it's the new buzzword, it's the future.

"But wait ... You are saying we have to publish every single one of our transactions to a public database that can be read by our competitors? The question is how can you have the benefits of the transparency of the blockchain without compromising your privacy?

"There is a wonderful area of cryptography called zero knowledge proofs that is somehow magically using a bunch of algorithms involving mathematical transforms on binary circuits to do exactly that."

Buterin mentioned a project called Zerocash in this regard, which puts zero-knowledge Succinct Non-interactive ARguments of Knowledge (zk-SNARK) into a bitcoin-like cryptocurrency. Zerocash creates a separate anonymous currency, existing alongside a (non-anonymous) base currency. Each user can convert (non-anonymous) basecoins into (anonymous) Zerocash coins.

He continued: "There are also many other applications of privacy ranging from things like proving that you are a reliable trustworthy person by some kind of reputation metric, or identity registry system, without actually revealing what your specific name is. Figuring out how to integrate that into Ethereum is one of our primary focuses."

The move to proof of stake via the Casper algorithm and upgrading the Ethereum virtual machine (EVM) are also high on the agenda and the subject of many of this week's talks, said Buterin.

"Initially I thought that Ethereum was a thing that would be used for people to write simple financial scripts. As it turns out people are writing stuff like Augur on top of it. So figuring out how to make the virtual machine really work is another topic we will be discussing this week."

I don't think so but I think that it will probably be released after the official GUI wallet for PC. An android wallet for Ether would certainly be a great idea as it would attract a wealth of Android users from around the world, and thus this will result in mainstream adoption.
