Some altcoins on the other hand do offer some innovative things to improve efficiency through cost reduction (p2p often beats centralization in this regards).
I agree. Bitcoins doesn't really improve anything in the world except the part about finance. Bitcoins are just a medium of exchange and it doesn't really improve our lives in a way that we can efficiently improve aspects of it. But bitcoins could speed up our financial institutions. However, this part of life is not a bottle neck really.
You are using bitcoin and you don't know what can it do to your country? Does not really improve anything? Think of it, you earn money from bitcoin, bitcoin has its value, that means you are earning money externally, you are making a new source of money and adding that money that you've earn on the circulation of money. That means, good economy, you must read articles about it.
If bitcoin improves finances it's already something, and something very important for a country. There are some countries where population suffer with depreciation in their currency. Every day the money values less.
They become poor each new day with a terrible currency, it doesn't give them the chance to store money for future purposes. That is one reason how bitcoin can help them a lot, just one of the reasons...
