April 1st joke aside, there's as much chance of a country adopting BTC as its national currency as there is of adopting Apple/Google/Msoft shares as it's currency, but that doesn't mean it won't become a popular investment just like the above shares.
It has so much more potential than any of those shares though. It could creep through the financial soil like fungi, without being even noticeable from the surface.
At the time being though its use is so limited in terms of beign able to use it daily. Yes there are big companies that use it, but how often do you need a new Dell? or shop at overstock? I mean yes it has
potential, but for the time being its relatively worthless compared to these multi billion dollar companies stocks
Because its still mega new. But all it takes to accept bitcoin in your shop is
1) Getting an address
2) Printing the QR and putting it on the desk so people can scan it and pay you
DONE! How fucking amazing is that. Imagine all the paperwork you would need to start a business the traditional way.
Bitcoin is going to be such a fucking success that people is not even able to grasp what we are dealing with yet.
First, your bitcoin will someday be hacked either from your server wallet or from your exchanger's account.
Second, you need an auto generation/confirm system to make different address for each client which lead you to point one.
Third, all the paperwork you need to do with shady exchangers are huge.
Fourth, just go
accept fiat from bitpay like everyone else please.
How im lying? You can make an address in a cold storage wallet in your house (will NOT get hacked), then use this public address to accept BTC on your shop. Whenever you need BTC get it out of your cold storage, whatever amount you need (just like having a safe with cash, and putting the money you need for the day in your wallet, in this case in your smartphone etc).
You can use a mixer after extracting money from your cold storage for more anonymity, before spending it or moving it elsewhere.
You don't need to rely on third parties. Bitpay doesn't need to be the new monopoly to accept payments, fuck that.
As for exchanges, there will be a day where you don't even need to convert to fiat because everything will be easily done thought BTC. If you still some fiat for whatever reason, you can get it using LocalBitcoins if you don't want any paperwork. Problem solved.
Bitcoin isn't a thing that is related to something bad. We should make it connected to some good things.
