No doubt in my mind that the big winners will be those who beside offering a secure and safe storage of value and means of exchange also offer real life solutions that improve our lives. It's like having your cake and eating it too: a store of value that is a thriving business too!
Would many be put off by the thought that it's too good to be true?
They may be put off due to their own ignorance of the technology and how it can be achieved via the blockchain. The transition from managed 3rd party services to decentralized services will take time as it is understood.
No doubt about it. It all comes down to not fully understanding what we've got between our hands. By the time it is fully understood on a wide scale, everything will be fully valued.
