Entrepreneurs who are copying business models from an original country and trying to implement those models verbatim in their own countries generally are not able to calculate the risks properly, actually that is why they are copying in the first place.
Obviously, different markets will have different market dynamics: purchasing power, demographics, openness to innovation, state-level regulations, capital accumulated, and the backing of a sound financial infrastructure. All will affect your copy differently.
However, there is one more important aspect.
Checking whether the business was financially viable in the original country!
In many examples these founders are just copying models that are not even proven to be financially viable in the original country, i.e. no prospect of positive earnings and cash flows despite the growth.
