Cohn believes that world will have global cryptocurrency in future but it will not be a Bitcoin.
The future will have simpler global cryptocurrency
The solution for a simpler global cryptocurrency is available with bitcoin, they need some great front end development and wallets that can be used by anyone and it will happen in the near future, even now we have mobile wallets which is easy to use and transact the coins without much fuss and i am sure in the future we will have some integration with mobile phones where you could send money to your contacts with the help of an app which could link every contacts to the wallet.
I'm not a big believer in bitcoin. I am a believer in blockchain technology. I do think we will have a global cryptocurrency at some point where the world understands it and it's not based on mining costs or cost of electricity or things like that.
He has the wrong idea about things as the price of bitcoin is not based on mining cost or cost of electricity, it is simply supply and demand.
