What would you say is the main reason that it's harder to do international business than a local one (speaking of digital business era)?
I think it's better to looking for what the needs of the people around you first, I mean if you want to create new opportunities, you have to think what the needs of people around you are, solve their problems with your ideas so that your ideas are recognized by people around you and then you can spread your wings all over the world.
That is the SCAM artist did in the past years which is why crypto was flooded by ICO scammer who thought their project solves problem and needs to be tokenized. Projects are good but it has to be well thought of that it wouldn't sound like a joke on its own.
Almost every possible idea were explored already in crypto so if you can create something out of your idea but will only become centralized, it may still fail in the end.
