I remember Lauda told me some months ago that there is nothing going to happen like hard fork in bitcoin's life.
You must be mistaken, I was probably referring to a specific hard fork and not all hard forks in general.I'm not an expert of bitcoin but look likes very necessary to do the fork.
if you are not an expert how do you know "it is necessary to fork"?!!Can anybody here create a easy to understand explanation to what this is all about? Cause it has become very confusing what is going on with Bitcoin Unlimited and it wanting to become an alt coin and ETH becoming it's own from starting as toting itself as a smart contract. 
You probably need not worry about it in that case. You could just read up about hard forks in general, which would be a decent starting point if you wanted to.
