what if one day all the trade edges on which I depend to make a living are all gone; what if they change/make the rules to push me out of the games; what if the dynamics of the business change against me; what if it is impossible for me to profit from trading anymore; what should I prepare for? what should I do? how would I know it before wasting resource but only to achieve a final failure when this kind of crucial changes happen.

Life is full of changes.

Life is full of changes.
