That is still to be seen, I guess. The biggest advantage I see here is the semi-anonymous nature of having your money on blockchain. Nobody can tell you how much you can own and where you must have it. I like privacy and I would go lengths to achieve it, but as I said, it's yet to be seen in the future, how secure blockchain really is. We all heard of 51% attacks lately, which have been executed on smaller coins, so that brings up some concerns.
