Why would you buy a bottle of milk with something that costs 1000 USD? Bitcoin may have been intended for small value items originally, but that is no longer the case. Today it makes more sense to use Bitcoin to buy houses and Lamborghini's (yes they accept Bitcoin as payment now). While Litecoin could be used to buy televisions and household appliances, and perhaps a faster more lightweight coin like Feathercoin could be used for everyday items such as milk. Think of it as a tool, you 'could' drive to the shop in a Truck/18 wheel tractor trailer unit but it would make more sense to drive a sports car
(you have to use the right tool for the job)
You clearly have never used bitcoin nor do you understand how it functions.
i love how people exadjurate confirm times required to process a transaction
imagine bitcoin replaced the common banking system (we know it wont, but it can certainly work alongside)
people can store their funds in safety deposit boxes (personal wallet clients)
for ease of use they would put their funds into bank accounts/card issuer EG a certain amount of satoshi's into a third party escrow services/offchain transaction service that's pre-confirmed at deposit, allowing for instant transactions.
then the third party service/bank can move funds across the world instantly to compensate the retailer/recipient and they can be sure its confirmed at the very worse 10 minutes.
This is my dream... Forget gold standard (just like the governments have done), the day 'bitcoin standard' becomes common place and treated as a worldwide currency... I can see it now; universally accepted paper money backed by REAL bitcoin (not government lies), pre-paid debit cards containing REAL bitcoin (yes albeit controlled and held by by a third party, all the smaller transactions will be done off-chain) , heck why not have credit cards, loans, mortgages, 5% interest on deposits... Yes, i know i'm basically describing a bank, but the big difference is everyone is no longer relying on only a fiat currency that the world governments can print/devalue at will.
Obviously the lending and interest on deposits part of this idea would only work if the value of bitcoin remained stable compared to the rest of the fait currencies, which is a problem i guess, so the only solution would be for bitcoin to become the only trusted currency (which isn't impossible, but not likely any time soon) - wages, taxes and all sales/purchases transacted in bitcoin, only then would that work.. I know it's unlikey but not impossible... i suppose that's why i called it a 'dream'.
It's a shame there are so many people who will blindly use fiat currency without stopping to question, why year upon year does my money become worth LESS AND LESS??
