I guess you have no clue about blockchains otherwise that many companies go into it because it can used for many things and it is safe. One example are big airlines because as a booking system but there are surly a huge potential for a big variety of fields for many companies and will be the future. I think you don't understand blockchains otherwise you wouldn't give this comments and by the way it is safer but to understand you have to inform yourself first.
Indeed it has. The best observation I have seen of this was of a couple who were given a free upgrade on a flight I was on from Emirates. The woman stood there looking at us all in cattle class with utter disdain in her eyes before she closed the curtains.
I was in the queue behind her so I know she got the free upgrade.
Low and behold we arrive in Scotland and she is going through immigration telling everyone how she had paid for business class and shouldnt have to wait along with everyone else.
I will not repeat my comments here but suffice to say she was a laughing stock within seconds.
