Devils Advocate

Hey guys,

I'm a huge believer in Blockchain Technology.

With all the recent trends discussing whether or not Bitcoin is in a Bubble (I believe BTC itself as a currency is in a Bubble)

How do you guys feel about the application of Blockchain overall?

Pros: I think my blog speaks for itself

Cons:

Most UI's look like they're from the 90s
Difficulty understanding how to setup Mining / Wallets
Risk of losing funds due to 1 wrong keystroke (Send/Receive Address)

What are your Pro's and Con's?
