Hey there Seb! If you really want to learn to use a balisong, you're going to want to replace that cheapie. It's not that you can't flip one, it's that you can only flip one for so long. Sadly, your knife is going to break if you use it every day. But, you probably didn't pay a whole lot for it, so no big loss.
Here's what I recommend to everyone starting out, who isn't comfortable spending tons of money. Buy a Jaguar (if you can in Germany). They're just a little more than twice the price of a china cheapie, but are more than twice as good. Now, the Jaguar will do you just fine, until one day... *POP*! A hinge pin breaks and your knife just won't work. Do not be alarmed

, it is easily repaired by following the directions
here, courtesy of
Balisongxtreme. That Jaguar will last you years if you maintain it properly. In fact, the sooner you replace the pins, the better, because the fix is stronger than the original.
And once you become hopelessly addicted to balisongs, then you'll have no problem spending a week's earnings on one
