Ethereum is interesting, but it isn't scaling.Exactly it's the exchange not the underlying currency. Crytpo 101 is don't leave large quantities of digital currency on an exchange account
What do you think about ethereum and others? Personally I'm not interested in bitcoin but most here still think bitcoin is the only digital currency
I do think the idea of smart contracts is interesting, but I don't see how they'll work in practice.
Lets say we have a crypto contract, what happens when we one party says the agreed act took place, and another says it didn't. You still need some sort of trusted third party to make the determination.
Then it's a simple escrow service.
Bitcoin gets all the attention, but I think the interesting stuff is in other coins.
Zcash & Monero are very interesting as they're an actual fungible currency. ie they can't be tracked.
I also think Monero and it's plan to be ASIC resistant is interesting.
Iota has a lot of neat ideas, but I don't think it has traction.
Overall I think the future should be a private blockchain, but I can't imagine the authorities will be okay with that. They really really don't like having a money supply they can't monitor and track.
Think of how much they have fought widespread crypto, and the current talk about encrypted DNS.
They really don't want people to move money secretly and freely. Why do you think they have declaration rules with how much cash you can carry into a country.
