Nice! I'm planing to open a caffe in Belgrade, we have a restaurant where you can pay with BTC but not a caffe like this. I think it would be brilliant, because there is actually a lot of people from Belgrade that are using BTC. What do you guys think? Any experience with caffe where you can pay with btc?

There are some small issues that need to be fix. the main one would be a faster way to verify if the transaction is confirmed or if it's broadcasted to the network, it's not realistic to wait 10,15 minutes (yet only for 1 confirmation) to pay for a cup of coffee.
There's this trade off of time vs. security, you either should trust the broadcast (unconfirmed transaction) or wait for the first confirmation.

I'm researching different methods of fast verification and this is a great experience to see how each one works out in real life situations.

Another issue is privacy that you should not reuse one address for all your transactions. The other challenge would be the security of private keys that I assume I've overcome this with some basic cryptography.

and also it's always possible to get a 3rd party like bitpay to go through all this trouble, but I prefer to have everything on my own hands, even if there would be any blames (hopefully not)

More and more business begin to accept bitcoins, but why the bitcoin prices are falling?

Victoo is right on this, and also most of the ups and downs in bitcoin prices are basicly the changes in supply and demand (bid/ask) in the market. we have a long way to stabilize this with the number of merchants that accept bitcoin.
