From my own opinion its a better way of accumulating wealth and secure a perfect future of cashless policy
Too early to say this. Not only because people arround the world still need more time to accept the tech and adopt it, but we can't deny the fact that bitcoin can't replace all the circulating FIAT arround the globe. In a recent analysis, 1 bitcoin should be worth $1 million if we aim to replace just the dollar currency.
Without to forget that bitcoin is still in early stages as a global currency and its network still need to be maintained by devs in order to make it stronger and solid.
I disagree about the first sentence you've said. It was never too early when understand the whole Blockchain and how cryptocurrency works, that alone can conclude that we have a brighter future ahead than those people who don't understand what cryptocurrency really is, unless the Government all over the world starts to see it that way. Japan is the first ever country who adapts Bitcoin as a way of payments or cashless transaction, if I'm not mistaken.
And with that, I can proudly assume that it helps their economy so much more that is why their country is richer and advanced than the other countries when it comes to technology.
