Potential ways the banks and governments can try to stop bitcoin

Do you think think bitcoin has been brushed away by banks and governments in the past few years?

Are they now taking notice?

What could there plans be?

With many countries looking like they are going to fade cash out and adopt the electronic payments as the favourited methods of banking, take for instance the large bank notes which have been withdrawn from circulation in recent times,
Chipping bank notes so they can trace every move we make,
some banks not accepting cash deposits,
The cashless world seems closer than I ever imagined,

This was predicted some 38 years ago and was said to be happening by 2018,
Let's be fair it's not going to happen by then but it's fast approaching, greedy governments and banks riddled with corruption looking to steel more from us in any way they can.

Is Bitcoin safe? What's your thoughts on how they can try and bring this down? Comment below I'm really interested in some ideas of what you may think will be there ammunition for the war between bitcoin and the banks,
