I think that one benefit to personalized learning that is often overlooked is the transparent and clear assignments.
My high schooler was lost in his math and English classes and it was impossible for us as parents to help him at home. The teachers did not use the on-line system at their disposal to share upcoming assignments and due dates. Assignments were only posted on line after the due date and with no information as to what the assignment was.
Upon moving him into on-line classes for English and Math, he is now learning the material, able to know exactly what is expected, and is getting much better grades. It is unfortunate that in our case the solution was to remove him from the classroom and all the benefits having a teacher brings. I continually try to get my student's teachers to make assignments available on-line but with amazingly limited success.
All currencies and even gold/silver/platinum only have value because people BELIEVE they have value.
No. Gold, platinum and sliver have actual uses that contribute to their value. While much of the value may be speculative, they do have intrinsic value which is specific to each of them individually.
Bitcoin has no similar intrinsic value that isn't easily copied (and possibly improved upon) by any number of altcoins.
