you have to be expert like microsoft to be copycat and thrive. Else if you are doing something which you have skills and knowledge of nobody can exactly copy your idea and customer service. Still there are pasmina, garment and carpet industry in Nepal. The people who tried to copycat did not last. But who have skills and knowledge are thriving to date in any industry like waiwai (many chau chau sprouted and vanished), bhatbateni (lots of sprouted competitors) etc etc.

Look at those travel agencies sprouting in Nepal. Some thrive some don't. Who have great customer service can attaract, others die.

All human being should know teachers give everyone in the class same lecture and homework but not all the student come first.

You do not have to look at other countries for small business, there are lot of examples in our own country.

If you think about all the hurdles, you are better off not doing business. 100% security not guranteed anywhere in the world.
