Trading can be view as educated guessing especially when you trade just with one particular asset(this sort of as Bitcoin). You solely rely on the estimation of how the currency is gonna evolve.

Almost everything is just about calculating on probability.
Business is all about finance and accounting. You have to make mathematical calculations, the ratios, the propositions, the shares and all that mathematics attached with business. You cant move forward if you dont know how to make better decisions on facts and figures. Like you said, it is only probability that is going with you along the path, and you become capable of taking good decisions.
