Cabal Rider question

Hi all, a friend of mine asked me why CR EU(new version) has the "BUY" and "CHARGE" button...after some time you will must buy the bot to use it????

i had this thing at beginning too....i played just 1 day than quit cabal so idk if u have to pay for it....there were 2 windows

1 - reg one and after u reg it appears this thing with buy/charge
2 - the main one....login there and start game....so just close the buy/charge one

Oh well, after i readed some things from cabalrider forum, currently Cabal Rider it's free, but in future you will must pay to bot with CR.
