10 Years from now..
Full disclosure: I am not a cryptocurrency expert, and have only started reading on the technology for the past few months now.
Hypothetically speaking if Bitcoin were to get worldwide adoption and replace fiat currency to become the primary currency then each bitcoin will be worth close to $1 Million - isn't that fascinating!! About 78% of the max 21 Million bitcoins have been mined already, which kind of breaks my heart since the opportunities to mine few dwindle every single hour. With the technology picking up 'steem' it would have been exciting for people to jump in with their advanced, custom built hardware to mine coins but the incentives continue to decline. A few million of those mined coins are missing and/or have not been accessed in a long time. Many of them belong to the legend - Satoshi, imagine the drive and hunger to recover those if bitcoin realizes its potential.
But let's imagine a world where Bitcoin is the only currency available and there is no regulation. In all probability, financial institutions will be out of business meaning that I would be without a job. Trade would become more direct - peer to peer with no scope for the middlemen. Borders would be only in terms of physical barriers and the role of governments will become less in regards to trade. People will have more power - which can be both good and bad. Lesser regulation on restricted items may reduce black markets and potentially alter the actual consumers of those products. The impact on global economy is huge, and at this point we are only discussing block chain 1.0
