Yes I believe bitcoin can be very usefull for everyone in the world. But I think bitcoin will not reach it's FULL potential any time soon. Maybe in 10 or 15 years hopefully I can buy my groceries at the local supermarket with bits!
yeah I also believe that bitcoin has the potential to become a mainstream currency in the future. I wish that I could buy anything in the supermarket with bitcoin. I'm sure the deployment and adoption of bitcoin will continue and perhaps 15 more years. we could see everything
