cryptocurrency could decrease the fee that has been used for international trading if it works right way.
but these days, it's quite overused for any kinds of industry.
it will be someday falling. because people don't need to use that.
but i'm quite sure some kinds of blockchain will be used at future.
So, need to study about it with own studying about it.
Do not just hear other's opinion. most of them are not professional even developers also. and the price of cryptocurrency might be over estimated but i don't know also.
anyway, we need to learn, and read all whitepaper properly.
ask to those team before invest etc.
all kinds of efforts needed actually.
