I had a friend preaching IOTA to me. It sounds like most genuine alt-coins: a solution to one or two problems.

Ethereum is certainly going to have to deal with the file size of the blockchain. And it's in the pipeline. And that's a strength of Ethereum right now. It's got a robust and tested development team in a position to solve these problems as they arise.

I really have to get my head around the shift from proof-of-work to proof-of-stake, which is the next major change.

The esoteric nature of crypto in general is definitely a hard solve.
