If the facts are like that now, what is the meaning behind mining crypto coins?
Is it the hope that one day the banks won't control out money or everyone just hoping that their coin will gain value one day?

Why crypto currencies don't get enough value?
Is it becuase there are too many kinds of coins outside now?

So if I don't have ASIC miner at least, then mininig isn't worth it? 

As far as I know, and I researched this deeply, my GTX 750 ti has to be the most profitable GPU card today.
The problem is whan I checking in this site http://www.coinwarz.com/calculators it says that almost any coin is not profitable for me. The only coin that says it profitablr for me is pheonixcoin and the developers said that I can't mine this coin by GPU anymore.

Is there no profit by in crypto currencies even if I got the best GPU?
