This is something I am painfully aware. We like bitcoin, and we use them, and expect them to take over the world (or so we hope). But the side effect of this would be to take away the power of governments to print money. Many people like this. Printing money has always been used (also) to fund wars. You take this away, and wars will be harder and smaller. More like the middle ages wars, were a war was not a global nation effort. Although of course technology is also responsible for the global nature of war. So if bitcoin takes away some power from the us or russia or china... Well that's ok.

But printing money is generally a tax, and it is a tax that hits especially the people who hoard the money, and do not put it to any use. If your money is invested, and there is inflation, you will likely get your money back. But keep it under the mattrass and it will lower its value. And where has this value gone? In a sense it has gone to the government that printed the money.

It is easy to say that the money printed has not been put at good use. But if you just look at the difference between countries with double digit inflation and failed states you will notice that failed states do not have a working government. There are warlords. Rape and violence are rampant, double digit inflation are terrible places to be, but are better than failed states, as somehow are still working.

So, as I am worried for Italy that with the Euro has lost the power to print money to get out of debt, so I think that bitcoin is great.... but might force governments to be good administrators of their digital gold. And politicians (elected or otherwise) statistically are NOT good administrators. So I am worried, and I understand Bangladesh.
