1) Bitcoin removes the counterparty from the currency. You do not have to trust a government. You instead have to trust in mathematics and the stability of a self-regulated community. (as such there is still some trust required)
2) Bitcoins are cash like and are superior to cash on many levels (money on your bank account is not cash)

Here's some homework for you: try to do a cash-like transaction with someone in another country

Hehe, first post and probably your last?

Is it just me or do recently a lot of accounts pop up, crating on single thread and are then never seen again.

But just in case this is a real question:

Bitcoins provide the usability of cash, although you can instantly pay them in every wallet world wide.

This usability provides value.

The fact, that they can't be printed instantly by anyone (infation resistant) increases the value even more.

And then they are only a few of them + most of them are horded and not available on the open marked, causing a high price.
