As we know for sure that global market is counted in multi trillion dollar industry and this keeps getting higher in value day by day and year by year, I doubt that crypto currency may at a time will disrupt this industry,

The doubt is but obvious because crypto currency as a whole including BTC + ALTCOINS together is not even amounting to the trillions or so and thus it is just little toy in a big toy shop. It may not even impact it because it is global stuff, and traded all over the world at the same time and hence also gets too much diluted over the time.

This is why crypto may not have any impact over the global Economy whatsoever.

Any thought reading this?
