Since Bitcoins do not have a physical form, it cannot be used in physical stores. It would always have to be converted to other currencies. Cards with Bitcoin wallet information stored in them have been proposed, but there is no consensus on a particular system. Since there would be multiple competing systems, merchants would find it unfeasible to support all Bitcoin cards, and therefore users would be forced to convert Bitcoins anyway, unless a universal system is proposed and implemented.

I first learned about Bitcoin in 2011. I remained skeptical / doubtful that it would amount to anything until the Cyprus bubble of 2013 after which I started to really dig in to it.

Right now the only reason people are investing in bitcoins is because it is seen as a way to make money. The value of Bitcoins has soared over the past few months. Right now (8 December 2017), one bitcoin is equal to £11,410.56 or US$15,327.70. Less than a week earlier one coin was worth $12,000. It’s gone up 1,300% in 2017.Back in 2009 when Bitcoin first appeared, $27 might have bought you 5,000 Bitcoins. If you’d have bought back then you’d be sitting on a nice little nest egg.

Bitcoin is peer-to-peer and open, yet secure and nearly frictionless bitcoin allows exchanging value over the internet without any intermediary and gives its users access to their balance through a password known as a private key. So it’s private, secure and at the same time,open.
