Unless we all want to lie to ourselves, in most places now, cryptocurrency is not being used daily for life stuffs and all we are just so keen about is the profitability in the long run. Sure, things would change over time as cryptocurrency starts getting more established, development in the blockchain sector keeps improving and we starts seeing usage and adoption by merchants, but for now, asides from being a payment means for jobs done across boarder or whatsoever, which is good enough anyway, there is no other usefulness.
