Perhaps my favorite part about the blockchain is the improved transactions. The decentralized aspect allows us to transfer money directly to the participating parties with no middle men as you articulated.

The security aspect is also a huge plus. This distributed ledger technology allows us to trust those we transact with, again with no centralized authority.

You are right that a lot of people believe that crypto currency is in one big bubble. However, I continue to remind people that even if it is, the currencies are just the byproduct of the underlying technology. Just like the . com bubble in the late 90's, a lot of crypto currencies will go bust. But, as you articulated here, the blockchain will continue to grow.
